The big thing in games right now, at least until Halo 3 comes out, is Bioshock. This was pitched as the spiritual successor to System Shock 2, a good game in its own right. (As an aside, I never did finish SS2 due to a bug at the very end of the game that prevented me from killing the boss. System Shock 1 sits atop my Pile of Shame, after I picked it up super-cheap at the flea market.)

Bioshock is good. Really good. And yet for me, it's failed to achieve the obsessive state that I get into with games which just really jive with me. The obsession that means once I get to work in the morning, all I can do is think about playing the game. Then I go home at lunch and play for an hour before pulling myself away from the computer, going back to work, and thinking about the game until it's time to return home. It may be that I'm just not capable of reaching that state with a first-person shooter any more.

It's a still a really good game and I look foward to finishing it.
