cannot wait for infinte to come out, bioshock is definitely one of my top 5 games (that i have). bioshock 2 was ok, single player seemed half-assed because of the multi-player, but i still enjoyed it. (wished the big sisters were more random, the were too easy to anticipate)
anyways, i'll probably buy this just because it has the bioshock label. i like the shift out of rapture, it was starting to feel "used up". everything looks great about infinite.....but that could be just because i have always loved bioshock.
p.s. if you have bioshock 2, i highly recomend the minerva's den add-on.
