I have three perfect saves in Final Fantasy Tactics, so that's many hundreds of hours right there. Getting all the buried treasures in Deep Dungeon by itself probably took hundreds of hours, not to mention getting every single character with every job skill maxed out. Cloud, especially, takes forever.
Fallout 3 and Fallout New Vegas also clock in at several hundred hours each, especially with mods. I'm sure I've spent tons of hours with Suikoden 1, 2, and 3, as well, getting all 108 characters.
I'm not even going to guess at WoW or Ragnarok Online.
