Capture the flag and movie night sounds like fun. I was playing capture the flag on Baker Beach (SF, CA) pretty regularly until I twisted my ankle going down the mulchy hills.

I tend to like strategy games and/or shooters, with adventure-style plots as a nice optional bonus. I'm not sure that I want to get involved with a group of friends who all play video games together -- while that's clearly better than just playing alone, historically playing with friends has just been an add-on to the solo habit. E.g. if I play 3 hours a week of Halo or Alpha Centauri with a friend in person, I'll play another 15 hours on the same game against the computer trying to playtest new strategies.
