Sadly (and disturbingly) I have DOZENS of games I've bought and never played. A lot of them are games I buy, play the opening few minutes of just to get a feel for what the game is like, then put away to play properly "later" when I have time, only to realize months or years later that I STILL haven't got around to it. And then there are the games where I haven't even got that far. The reason I don't play a lot of them is I never get around to beating their predecessor being installments I haven't worked my way through yet. A lot of them are games where I'm already playing too many other games of the same genre at the same time and want to clear my palette a bit before starting them. And some I simply don't have the english language patch for yet.
And I'm not exaggerating- I do mean DOZENS of games. It's because I leap at the chance to buy a game if there's any possibility I might not be able to get it if I miss the chance (I find that if I pass up a game at the first opportunity, I regularly won't ever get another chance to buy it). You want a complete list? OK, but this is gonna freak you out:
