Ah, THIS is the thread I should be posting in, not the "Last Game You Played" thread. I almost never put a game aside until I beat it, unless the game is very annoying in its difficulty to the point where it just aggravates me (~3-4% of games I buy, typically). If I can't "beat" a game (such as Minecraft or Spore) I never play it in the first place. I'm too OCD when it comes to stuff like that.
Anyways, the last game I beat was Syberia on PS3. An okay adventure/puzzle game, but I'm not sure why it has such a legendary status. A lot of the game is just you running between locations, and the dialogue is a bit awkward and the game ends right when the story gets interesting.
