@capaho: I try not to get hysterical or anything, but the injustice(ha ha) of it all annoys me. How long did this woman play the game? Because after 6 hours with it, I could lodge a valid complaint that could help justify the score, but she apparently had time to play it to completion AND make some (presumably) significant headway in the multiplayer mode but she still missed the fact that the combat is less consistent in AO than it was in AC. Instead, she writes an entire review that basically amounts to: it's Arkham City all over again. Oh, and multiplayer sucks. 6/10.
@UpInFlames: Don't tell me it's a positive rating, because it isn't 6 on a 10 scale, it's a 3 on a 7 scale. 1s, 2s and 3s are reserved for games that are unplayable- games that suffer from glitches and bugs no matter where you look; games that suffer from a consistent, progress halting glitch; and games that are simply mechanically unsound.
