Good Grimace, yes.
When I was in high school, my group would get off school on Friday, migrate to my basement, watch a movie (usually adult), then start gaming (first game was always D&D). We would game until 2 am, watch another movie, then crash in the spare bedroom. At about noon, everyone would be awake again, so we'd order pizza, make a few crank phone calls, watch another movie or some eMpTyV (it sucked worse then, because it bothered to play videos), and game again (usually TMNT, sometime Shadowrun when it came out, sometimes GURPS Special Ops) until the wee hours. Then we would wake again at about noon, play a short game (D&D or TMNT), then everyone would go home and do homework.
Nowadays, my group meets at a gaming store for four hours on Saturday, alternating games (D&D one weekend, GURPS Space the other), then at my place on Thursday night for about three, playing another game (D20 Conan).
My gaming tastes haven't changed as much (I've always tended to be a Real Roleplayer, with a bit of Loonie thrown in), though I GM more. I'm more rules-light than I was -- when I was in high school, I rarely GMed because I'd drive myself silly trying to handle all the rules I thought I should be handling but everyone else ignored. And I don't play any more angst puppies.
