OXM - One of the great tragedies of games publishing is that sequels rarely encourage us to revisit the original game. Book and film sequels don't have this problem, I suspect, because most are mere continuations of a narrative; a game sequel generally represents both the next stage of the saga (excepting non-narrative titles like FIFA, of course) and a new, refined and better-featured version of its predecessor.
A stand out game and masterpiece of a generation alongside MGS4 in terms of writing an story.
They should have an ad campaign for Bioshock Infinite of putting posters everywhere with the box art and "Would you kindly purchase Bioshock Infiite?" printed above it.
I'd buy it based on that =P
