Resistance 2, it is said to take 240 hours to unlock everything
maybe Fable 2, though it probably only takes 20 hours to play through, and 40 hours for everything, but you can have multiple playthroughs to be good or evil
Call of Duty World at War, I certainly spent ages playing 4 online, and this is meant to be very similar
Mass Effect, you can get it cheap (about £20 from game.co.uk I think) and you could have a 50 hour playthrough, and you can play it as different classes and either be good or evil... the possibilities are endless. It is cheap so you can also get Uncharted, which although short, is incredible, and if you can get Mass Effect and Uncharted for the price of 1 game, then you should definitely do it, as ME's length makes up for Uncharted's
