i tend to not replay games over long periods of time, so most replayed game would either be fallout new vegas (5+ play throughs, 20+ hours each), fallout 3 (7+ playthroughs, 30 hours each) or jack and daxter 1, i never finished it but when i did i went back and beat it like 8 times since it was the first game i ever had and as a sort of "fuck you, game" for scaring me as a small child. even beat it in one day once.
