Well since everyone pretty much ignored the last post, here is the second atempt to get you cunts to play this game,
by copypasteing someones review (cause I am too stupid lazy busy to write one myself)G-Senjou no Maou

Description:
You play the role of Azai Kyousuke, the son of a legendary gangster infamous in the underworld. You spend your time listening to Bach, playing God at school and covertly working for your stepfather, a ruthless financial heavyweight. This idyllic existence is broken when two individuals appear in the city - a beautiful girl named Usami Haru with hair you could get lost in for days, and a powerful international gangster known only as "Maou". Almost without delay, the two begin a deadly cat-and-mouse game, bringing you and your friends into the crossfire. Plotting, political intrigue and layer upon layer of interlocking traps are the weapons in this epic battle of wits.
VNDB
This game was developed by Akabei Soft2, and its the second title from this company that has been translated to english, with Sharin no Kuni being the first one. If you did like Sharin no Kuni, you will probably like this game too. I personally loved Sharin no Kuni, but I probably prefer G-Senjou no Maou over Sharin no Kuni (though its a close call).
Well, saying that, lets go with the review...
Structure:
First, I'm going to talk a little bit about the structure of the game, as I find this an important characteristic on a VN.
The game has 5 possible chapters, a special chapter for each heroine (except Haru Usami) and an epilogue (just for Haru).
The game structure is pretty similar to Sharin no Kuni, but it does have some differences.
You start with a prologue (which is actually chapter 1), which explains you about the setting, and also gets you to know the characters and their personalities.
As in Sharin no Kuni, each chapter has the story centered in one of the heroines, and also, if you want to choose an specific heroine's route, you will have to do it on her corresponding chapter.
The biggest difference with Sharin no Kuni, is that the story changes completely depending on who you choose. Also, when you make your decision, you will stop advancing chapters, you will likely have a different ending for the chapter of the heroine you chose, and then you will directly go for the heroine special chapter. So yes, if you choose Tsubaki from chapter 2, you will miss chapters 3, 4 and 5.
Also, as in Sharin no Kuni, every heroine has one good ending and one bad ending, except for one of them, who only has a good ending. Also, there is no harem ending.
This structure does help in making each character unique throughout their route (something that didn't happen on Sharin no Kuni), but it also does have the problem that some routes does leave some loose ends.
Plot:
Lets start by saying that this game is meant for the Haru Route, which is by far the longest, the most developed and the only one that leaves no loose ends with any character or specific situation.
As Sharin no Kuni, this game is full of mind battles between characters, and some very crazy plot twists, though it has a lot more of both things.
Though the main character is Azai Kyousuke, the big mind battles are between Haru and "Maou". The latest is the main antagonist of the story. A man of unknown identity who happens to be a genious. If you have watched animes like Code Geass or Death Note, you may understand if I tell you he is like Zero or Kira (with one big difference: on both animes you, the viewer, knows Kira an Zero's identity, here you don't). His main purpose is unknown, and he seems to love to toy with people, specially Haru (who would be like L from Death Note).
The game is full of mind battles between Haru and Maou, with both characters always trying to be one step ahead of the other. Maou clearly wants to kill Haru, and same thing happens the other way. Reasons of the hatred for each other, and also their past, remain a mistery until very late in the game.
There is also a big emphasis on the relation between Maou and Azai Kyousuke, which I won't explain on detail to evade any possible spoiler.
Of course, every mind game is accompanied with quite a lot of action. But the game has lots of comical reliefs, again, just like Sharin no Kuni.
There are some plot twists that may seem kind of forced, but in general, the plot of the game is not good, is awesome, or epic.
Characters:
The repertoire of character is quite diverse, and I would say its quite interesting as the heroines aren't your every day tsundere, kuudere and moe. They do have some of these thing, but they aren't so stereotypical.
Azai Kyousuke: I wouldn't say he is as good as Morita Kenichi from Sharin no Kuni, but he is kind of the same style. He is obsessed with money, and does a lot of shady business for his stepfather, who is a big yakuza boss. In school he wears a mask to hide hide his personality. His tone of voice changes dramatically and he acts like a social guy who is always fooling around. His biggest passion is classical music.
Maou: The main antagonist of the game. He is supremely intelligent, and a complete mistery. A great part of the VN has him as a protagonist, even though he is the antagonist (sounds contradictory). So we get a lot of his monologues. Who is he? What is he planning? What's the purpose of his actions?. Absolutely nothing is certain, but they do give you a number of hints throughout the game. I personally found this character exceptional. An incredible antagonist. A great villain. This guy is the main reason I love this VN.
His seiyuu is Jun Fukuyama, who is mostly known for his role as Lelouch in the anime Code Geass. He is just the perfect guy for the role because, as I said before, he is very much like Lelouch.
Haru Usami: She is an incredibly intelligent girl who has an outstanding detective capacity. Its seems impossible to hide something from her because she will definitely discover the truth by investigating a little (if not, ask Kyousuke). She has a profound hatred for Maou, though the reason is unknown. She is desperately trying to catch him. The look in her eyes changes completely when she gets serious, with the novel representing them as fierce red eyes. She is actually quite poor and has a part-time job. She can be very clumsy and speaks quite a lot of nonsense when she is not being serious.
Her seiyuu is Kawasima RIno, whom I personally didn't know of, but she did a great job voicing Haru.
Azai Kanon: She is the daughter of Azai Gonzou, Kyousuke's stepfather, which makes her Kyousuke's sister, though they are not blood-related. She is a famous ice skater who is trying to go to the olympics, though it isn't an easy task as Japan has only one spot. Even though she is the daughter of a yakuza leader, she isn't aware of it, and dedicates herself only to skating. She doesn't try to think about other things. Her mother was also a famous ice skater and she is always with Kanon. She is her former coach, but Kanon still calls her "coach".
Her seiyuu is Koorogi Satomi, who you might recognize from Clannad, as she also voiced little Ushio...which I personally found a little disturbing because of the hentai scenes

Miwa Tsubaki: The class chairman. She is a very innocent person, she trusts everyone and kind of thinks there is no evil in this world. She is a very positive person and she always tries to help others if she can. She is extremely devoted to her big family, as she is the biggest daughter of 5 siblings.
Her seiyuu is Kanzaki Chiro, who also voiced voice Oone Touka from Sharin no Kuni (though characters personalities are differents). Even though I prefered her job as Touka, she did a great job as Tsubaki. Also, I might be prefering Touka cause she was my favorite heroine from Sharin no Kuni while Tsubaki is the character I liked the less in G-Senjou no Maou.
Shiratori Mizuha: This character is kind of kuudere (cold character) but as the story develops (specially on her route) she starts showing more of a tsundere personality. She is the daughter of the director of their school and she apparently hates Kyousuke because she is aware of his real personality.
Her seiyuu is Kumiko Yokote (El from Shugo Chara). I didn't know her, but she did a real good job as Mizuha.
Tokita Yuki: She doesn't actually have a route, which is a shame cause she is an awesome character. She is a genious when it comes to talking, she is an expert detecting lies, and making people confess things. An artist when it comes to words. She appears late in the game, but is a very important character.
Her seiyuu is Hitomi, who is known for her roles as Primura (Shuffle!) and Sakura Yoshino (DC Da Capo). Her job as Yuki is simply remarkable.
Azai Gonzou: Stepfather of Kyousuke and a big mafia leader. For him, money is absolutely everything, and people are just "things" used to make money. He is a fearsome man, who besides of being big and strong, is also an incredibly intelligent person. There is probably no person who doesn't fear Azai Gonzou.
His seiyuu is Iguchi Denemon. I don't know about any previous role from him, but his job as Gonzou is superb.
Aizawa Eiichi: He is a friend of Kyousuke from school and mostly a comic relief for the story, though he also get some serious role at a certain moment. He loves more mature women, though he looks like a child. He acts very cute and innocent towards girls, but he's really quite a bastard. He makes quite a number of comments trespassing the fourth wall.
His seiyuu is Yuuki Kajita. He did a pretty good job as Eiichi.
The game does have some hentai content, but is minimal. Its usually almost at the end of a character's route.
Art:
Pretty much like Sharin no Kuni, but it does look more...modern. Real nice art in general. Very detailed.
Music:
Maybe this is the strongest point of this anime. I've heard a lot of great music in many VN, but I can clearly say my favorite OST is the one from G-Senjou no Maou. And how could it not be epic, because this game revolves A LOT around music. The name of the antagonist "Maou" means "Devil", and it was taken from Frank Schubert's compostion based on Goethe poem "Der Erlkönig", which means Devil. Not only that...the title of the VN (The Devil on G-String in english) is based on "Air on the G-Sting" which is an adaption made by August Wilhelmj of the composition "Air" made by the famous composer Bach (who happens to be the favorite composer of Kyousuke).
Most of the music from the game are adaptions from famous pieces of classical music, or sometimes, the original piece itself, which makes it impossible not to be epic.
Also, there are three main themes that are also great:
Anwser: This is the opening of the game, which I personally found really good. It is sung by Katakiri Rekka, who also made the main themes from Sharin no Kuni and the ending of the anime Higurashi no Naku Koro ni.
Close Your Eyes: An epic theme that is played close to the end of the game. I loved this one. Simply great. It is sung by Ayane.
Yuki no Hane, Toki no Kaze: The ending theme of the game. Again, an awesome theme (at least for me). It was sung by the group "Barbarian On The Grove".
Conclusion:
I won't go all the way to say is my favorite VN or something like that, because I've played quite a number of VN, but I can surely say this one is great and worth playing. The music in the game is simply epic, and the story is great. The only "bad" thing about this game is that there is really only one epic route, which is Haru's. The other routes tend to completely forget about the main plot: Maou, or they just give a lame explanation. I would definitely recommend to start by the Haru route, so you can completely enjoy its epicness without the possible "spoilers" you might find on other routes. Treat the other routes as if they were an "OVA" on an anime or something like that.
This game and Sharin no Kuni made me a great fan of Akabei Soft2, and now I'm always waiting to see if someone translates something from them.
I suppose if I had to evaluate this, it would be something like a 9/10 I suppose.
I expected great things from this game, having played Sharin no Kuni before, and what can I say, the game delivered.

Also if you don't want to install the game (do it, faggot) you can watch a let's play of some dude on youtube, who played through the entire haru route (other stuff is shit, don't bother). I wouldn't recommend it though, as the background music appears to stop everytime a voiceclip plays, which is like every 3 seconds. And you want to hear the BGM. Oh yeah, you can turn off the voiceclips in the game if you want to.
