I tried the original dn3d the other day (too young to have played it the first time around), and it was pretty damn cool. Not a great game, really - I got lost something bad and I don't really have the patience for looking for more than 5 minutes for the way out before I look up a walkthrough, and there were some places where you were taking heavy damage without feeling that you would've done better if you were more skilled, but still a good game. Looking at TotalBiscuit's first impression video, this doesn't look great at all. For someone like me who didn't play the originals a lot, the jokes wouldn't make any sense, and there's a lot of... standing around. Which isn't great in any game.
It feels like they've tried to make the game in the style that was the shit just before cover based combat became what everybody started doing (like, uh, I guess Doom 3), but felt the need to build it around a gimmick character. I hope the new Serious same games don't suffer the same problem.
