I play MMOs; currently it's WoW and EVE, with a bit of RuneScape when I fancy a change of pace. (I can't be bothered to link those things; if you don't about them you probably don't want to. ... What do you mean you've never heard of RuneScape?). One of the more interesting things about them as they interact with Real Life is the demand for in-game things for real currency, or vice versa.
And again, it's mostly Xbox 360 games.
