All time? Probably WoW. I've been playing the game for almost a decade now, off and on.
For short bursts? Civ 5. Every few months I'll pick it up and lose a week of my life to it. I'll sit down one evening for a nice game of Civilization, and next thing I know the sun is coming up. Angband is the same way for me. I'll pick it up, play like crazy for a couple days, die, then not touch the game again for months or years.
I also lost essentially an entire summer play Runescape in the early 2000's. I seem to remember doing the math that I spent something like 600 hours that summer farming lobsters, or something like that.
