Usually if our game gets corrupted we just restart the game if it was worth it, but out of all the games you have and have some you played in the past, which game's loss of data (game saves / patches etc) would piss you off the most, possibly to the point you wouldn't bother replaying it.
Oh and lets say the corrupted data also effects your trophy / achievements and online score just for fun.
