Well, to each his own. It was an overall well crafted and ambitious Shooter... On the Art side, it was too colorful. I wished they'd tone down the saturation and use a tighter color palette....more grayish-brownish...a little more depressive. Though that wouldn't have come good with the X360 fans.
Anyway, Bioshock 2 is now being developed at the new 2K Marin, without any involvement of Ken Levine. Maybe that's a good sign, since he just had to satisfy his 2K master first and foremost. Now that the franchise is successfully established, I expect that BS2 is going to be a bit more risky, more hardcore...you know what I mean.
