Does the average Joe Blow even know who Infinity Ward and Treyarch are? Don't they probably want just more of the same? I guess it's just a score, and if anything a negative review will push Activision to NOT just do more of the same, but BO is a good game. It seems unfair to dock it too much based on it doing nothing new. Of course I've heard the PC version launched with some serious issues, so maybe that played into this review as well.
Anyway, I still haven't even touched the single player. I've hit the level cap (50), prestiged, and I'm back up to 20 again. I'm loving it. I'd compare the move from MW2 to Black Ops more to something like a WoW expansion coming out. I get rid of old shit I didn't like, I get new cool shit, and I get to level again. I also get new areas to play around in. All of that is worth $60 to me. It's like those people who've been playing Counter-Strike for 10 years (or however long it's been out). I can feel myself heading in that direction with CoD, but with new games and map packs, I get new stuff once in a while, instead of spending a decade playing de_dust2 with an AWP.
