I will be buying this game just to support the fact it doesn't have multi. Multi is such a weak crutch and boring as shit.
Really? Buying a game JUST because it doesn't have multiplayer?
I hope you buy every single player only title on the market.
As for this game, my purchase was guaranteed the moment it was announced. Loved Bioshock, and this looks outstanding to me. The tower defense mutliplayer sounds like it could have been interesting, but if it wasn't up to standards I'm glad they cut it instead of releasing something half arsed.
