Purchased God of War Saga, kept the download codes and sold the game back for the same $20 I purchased it for.
Sold Dishonored after playing it a few days and realizing it wasn't for me.
Sold Pirates of the Caribbean (Don't remember which one) because I didn't care for it.
Sold Orange Box because I didn't care for Half-life. (Be gentle please!)
I know there are others, but I mainly sell games to finance purchases of new games.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
Currently playing:
Final Fantasy VI (iOS), Final Fantasy: Record Keeper (iOS) & Dragon Quest V (iOS)
