Bioshock 2 was a very good game to me. However, with my achievement neurosis, I can't help but try to get 1400/1400 on the game, which for decent players takes at least 4 somewhat thorough playthroughs. I mean, the endings ain't as emotional if you've seen them ALL at least once, and single-player campaigns shouldn't force you to milk 'em for 100+ of hours of replay value. Perfecting Bs2 would also require you to spend an expletive amount of time on Multiplayer, which incidentally is the same beef I have with Reach and AssCreedBro. Still, they're fun enough to preoccupy me (barely) until I do get the achievements, so I guess that's the silver lining. But no FATAL flaws in otherwise good games I can think of.
