What games did you finish multiple times?

Vagrant Story. Finished it at least 15 times

FTL, Prince Of Persia, GTA Vice City, X-COM: Enemy Unknown, Batman: Arkham City, Hotline Miami

Starcraft (the first one), Warcraft 3, VVVVVV, Portal 2, Mass Effect 2, Saints Row 3, Neighbours from Hell <- just from the top of my head

GTA: VC, Max Payne 1 and 2, NFS:MW, Skyrim

Diablo III. U have to beat it like 4 times to get a max lvl character, then u want prob 4 more characters thats beating the game 20 times to get a max lvl of each class. Then u want some hardcore characters. So to have a max lvl of each in each game mode (Softcore and Hardcore) u need to beat the game 40 times. And Im keeping the farming away (wich is in the same boring maps as the story itself)...
So yeah I beat Diablo III like 40 times or something like that

dead space

I've finished Far Cry 3 twice, and plan on playing it a third time on the hardest difficulty, I might stream it (why not).

I just got the DLC pack for Sleeping Dogs and was reminded of how amazing that game looks, I will definitely be playing that again now that I have a controller. I'm also planning on replaying Tomb Raider once I get a new graphics card since it only takes like 8 hours to finish and I want to experience TressFX.

I guess Far Cry 3 is the only game I've played multiple times. I've put lots of hours in Elder Scrolls games, but I've only ever replayed a few quests.
