I know it wouldn't be fair to score a game based on the merits of a game that hasn't even been released yet, but Gears of War isn't even on the same level as BioShock. Plus I never liked Gears of War's art style anyway. It was so horrible. Gear of War SUCKS!!! You know it to be true.
However you look at it, everything comes back to BioSHOCK.
