The canon in the first game was well...silly to begin with...and I never liked Jack.Furburt said:The Longest Journey didn't really need a sequel. It got one. It was pretty good, but unnecessary.
As for Bioshock, I'm still in two minds about the whole thing, I mean, it could very possibly completely fuck up the whole canon and make replaying Bioshock one difficult, then again, it could be a veritable Godfather II of sequels. It's just impossible to tell because they can't show or tell us much of the plot.
As for BS2
you = big daddy = pure concentrated awesome
