Borderlands
Red faction guerrilla was really fun for me , they give me reward for destroying stuff
Saints row 2 and bully. 2 of the funniest games ive ever played.
Well, if you liked Fallout 3 then you would LOVE Oblivion, it's made by the same people and it's the same exact style/gameplay (customizable character, main quests, side quests, weapons, items, etc.) it just that Oblivion is Medieval but you can do all the things you can in Fallout 3 if not more. You can cast spells and make your own and enchant items (if your into the whole ''power-up thing, you might like that kinda' stuff) and toggle 1st and 3rd person. The only thing that's different is no V.A.T.S :P I got it just recently because I played it at a friends house and thought it was great and like I said if you were a fan of Fallout 3 you'd definitely like Oblivion. Another great thing about it is after I got so used to staring at destroyed buildings, Barron wastelands and rubble in Fallout 3, I played Oblivion and found that the scenery was full of Lush green grass, plants, and tree's and it Has some incredible landscapes like snow-capped mountains and forests so you would love the open world wandering in that. Another great game is Fable 2 that's open world too and it's really fun. :D
I think AC 2 falls into that category.
Oblivion is an older game, but it is amazing. Also, if you're into open world racing, check out Burnout Paradise or Fuel.

My fav open world game is AC2, it's simply amazing. GTA4 is not bad as well.
Borderlands and Red faction guerrilla are very good.Oblivion and Prototype are also good.But AC2 it is just amazing,it is not like a FPS but it is like Prince of persia with a big open world to explore.
GTA IV
Grand Theft Auto 4, Saints Row 2, Red Faction Guerilla are my favourites.
