Got around playing Bioshock 2. Haven't played much so far (first couple of levels, about 2 hours) but it's good. Graphics are exactly the same as the first one, enemies so far are very similar (except for the big sister). They seemed to make the story fit, but it feels a bit forced.
You know you're playing a huge and menacing big daddy but it really doesn't feel like it. You can die fairly quickly and your drill isn't that strong, and essentially useless unless combined with plasmids (especially if you are fighting splicers with guns)
Playing on PC and the controls are a bit frustrating. Switching plasmids is horrible inefficient (press q or z). I guess it's because you dual wield now. I preferred the old system where I could switch back and forth. Dual wielding makes me a bit confused and I often hit the wrong button. Something I'll probably get used to I guess. Haven't tried the MP yet, will do after I beat the main game.
I also been enjoying Max and the Magic Marker:

It's like Lucidity (terrible game) and Crayon Phyics Deluxe mixed together. You can control your character unlike Lucidity and you can draw whatever you want, like CPD. Really good difficulty and solid level design. Browser demo is here:
