Oddly enough, RPGs have been pretty much the only games that I've played through more than once. I only recently finished Dragon Age: Origins, and all the DLC, then immediately started playing through again. I think the main reason for this was that my intentions for playing through again was to make the other choice. So, although most filler bits were the exact same, I was experiencing the other side of the coin.
The other games that I've played through were FFVII, FFVIII, FFIX, and FFX.
Whereas games like Fallout 3, I could only play through once. And at times I actually had to force myself to push on. I did love the game, but I found myself more bored than other RPG games.
I don't think there are many other games I could play through more than once, or rarely, twice. Or if I do play through it another time, it'll be some time (usually years) after originally completing it.
