Arkham Asylum's play time is about 8-10 hours without any side quests ( 10-15 with ). Ratchet and Clank will probably be about 10 hours also. I personally love both games, but if I had to choose, I say Arkham Asylum.
However the best PS3 game of all time is Uncharted 2.
Another great game is inFamous. ( As good as Arkham Asylum, with side quests is 10 hours, with is 20-25 hours )
