I've mostly GMed, but I like playing, too. My favorite genres are science fiction and old-school cinematic sword and sorcery. From the GM perspective, I have a homebrew fantasy setting I'm fleshing out more as I push things to my wiki. Otherwise, I have a lot of loose ideas for a science fiction thing, but it's not really ready for play just yet. I have run introductory games for new GURPS players a few times, and they usually go well, though a mix of new and experienced players is usually the best mix for me. As a player, I like games that don't require a lot of in-depth roleplaying and backstories and such. I like to have fun and relax while gaming, so I tend toward Action!, Dungeon Fantasy, and Action! in Spaaaaaaaaaaaaaaaaaaace. Thinking about it, my games tend to be Action! in ___, where ___ is fantasy, science fiction, whatever. I'm also a fan of really crazy games (GURPS Anthill? GURPS Rifts?).
