Would someone recommend me a game with a great replayablity and is so much fun(PC or Xbox 360)??? I need some offline, solo, singleplayer game that can be played for long periods of time, no matter what the genre is. for example, Elder Scrolls IV: Oblivion, Galactic Civlizations II, NBA 2k11, Grand Theft Autos, Half-Life(because of the mods, especially Gmod), The Sims, Red Dead Redemption, Rock Band, Fight Night, etc. Not games like Call of Duty(i said solo, so multiplayers not counted), Mass Effect, Alan Wake, Gears of War, Resident Evil, Crysis, Assassins Creed, , etc or any other that have a story and when the story ends youre only left with playing the same story again with different bonuses/gimmicks in the 2nd playthrough. Ive played these games and their really good but what i need is something that would keep me busy without having to change games immediately. Plus if the story is so great you would even tend to beat it in a hurry just to find out the whole story, thats what happened to Mass Effect. In GTA IV it happened but theres additional things you could do. Maybe theres a hidden game somewhere waiting to be played by me for a long time. Just keep em' coming.
