Cooperation doesn't imply certain numbers of other people, and you don't play "with" 40 other people in an MMO, I should know, I play one. I'd recommend mine (DDO) but it's more hub-based so you don't get quite as much open exploration as you do with, say, LotRO. My guild leader and I can 2-man any quest in DDO apart from raids, and we do--that's how we level rapidly most of the time, because pugs are erratic. And part of the fun in DDO is making it so your character can be self-sufficient. Due to the number of build options in DDO, you really CAN build characters that can do just about everything (except fulfill some of the ultra-specific raid roles) if that's what you really want to do. But a DPS-healer-tank is not that difficult to build if you want to sink time into it.GrimSheeper said:Also I think co-operative doesn't mean you can play with 40 people, but just with one other person to co-operate with. Yes, a five man group still co-operates, the way they do that is entirely different though.
The game is designed for whatever you want to do with it; witness the guy who capped a character in WoW without killing anything or finishing any quests. Oh, and Oblivion has a bunch of "kill 5 things because they bug me" quests, too. Not as many as WoW, but Oblivion doesn't have as many quests as WoW, PERIOD.
Oblivion had gobs of imbecile dialog and horrible voice acting, too, not to mention the persuasion pie you had to feed people.
Now, if you're looking for a game where you can level up your character by standing in the middle of the street and casting nighteye 5000 times, no, you probably won't find an MMO for that. If you're looking for a big open sandbox to explore where you can hang out with other people if you choose, most MMO's will fit the bill quite nicely.
