What game haven't you gotten tired of after years of play?

I'm not actually sure if this counts - but Final Fantasy XIV.
I played since the original game's Beta (not the re-release) and its been a great game to me.

I'm not sure it counts because I have times where I stop playing for a few months, only be sucked in a get later.
So I get tired of it from time to time, but its never for too long.
