I think Bioshock 2 is looking really great, judging by the gameplay vid it definitely seems to have the atmosphere and the combat isn't too slow paced (being a big daddy and all), but I just hope they fix the core gameplay. It ended up being really quite slow and samey. 'Go here, kill these guys' or 'Go here, fetch that, bring it back here' just repeated endlessly and once you defeated your first couple of big daddy's, it was no harder to kill the others than it was a splicer. I haven't even finished the first one due to this reason, I love the story, I love the atmosphere, I love the awesome level design but the gameplay does not inspire me to come back. I really hope they fix this in the next game.
