What is the longest game that you played through more than once?

For me it would have to be Baldurs Gate 1 with expansion (and 2, since you can go from one to the next if you carry over your characters/party).

I've gone through Baldur's Gate 1 twice, with two different parties. First time when I bought it back in 1998, again sometime in mid 2000, also went through BG2 twice. Right now I am playing through BG1 yet again thanks to the enhanced edition...

So whats the longest game you've replayed more than once?
