Ah yes, no3..... Well of course the Rapture in the sky idea is a complete 'WTF?!', but I for one am glad it's not set underwater again! The first game is definitely one of my fave games in recent times, and was foaming at the mouth for no2, but it was just too much - don't think I even finished it lol....
Like some others I would also have been quite happy with Bioshock staying as a standalone game, but still, it's coming, has been in development for 3 years now and there's another 2 years to go before release...... should be a cracker when it gets released!
