The neat part about WoW is that while you're involved with it, you'll pretty much stop buying other games. For the 14 months I was super-active with it, I probably "saved" hundreds of dollars that I would've been spending on 20-50 hour long games. That being said, I don't play it anymore because I got sick of the grind. The initial push to level 70 (or 80 once the expansion comes out) can be alot of fun. The "lets run this dungeon for the 15th time because we need a bit more rep/rare items" isn't so hot.
