Duke Nukem Forever is actually great.
On PC that is. The graphics are absolutely shit on consoles.
Don't listen to the "professional reviewers" because they play shitty console ports with shit graphics and shit everything.
Although the fucking physics puzzles are just rip offs from Half-Life 2 and make me pissed off.
I mean, HL2 was great, that is, the physics puzzles ruined the experience just like it does with DNF.
"rip off" or "parody"?
And, honestly, DN3D had it's fair share of "puzzles", too.
Granted, it was just "find closed door, get the keycard/find the switch, proceed", but yeah.
Oh, speaking of keycards: In DNF, you don't SEE them, but they are still there.
