1.) How many players in your group?
Two: EN board member SnowDog and another player. Lean times. Two players is the bare minimum, and sometimes it feels pretty thin. But interviewing random players hasn't worked out yet; we've had pretty lousy experiences with posting information and trying to find a new random player. The last guy was a guy with a family (and so I think: "mature") who showed up and then lied on his important rolls in plain view. Sigh. He didn't work out. SnowDog and I could write a long essay on this stuff.
2,3.) Do you DM? Do other people in the group DM, and how many?
SnowDog and I take turns running campaigns. Right now, I'm enjoying playing in his game.
4.) What's the Male/Female composition of the group?
All men here. I keep trying to bring my girlfriend into it, because she'd like it, but we'd have to play something simpler like Spycraft or BESM to get over the "encyclopedia of rules" issue. SnowDog's wife used to like to play, but also doesn't enjoy a huge amount of rules, and is the worst dieroller I've ever ever ever seen.
5.) Got a good gamestore near you and what is it?
Yup: Danger Planet on Spruce Street in Waltham, Massachusetts. Nice people, decent selection. They don't get RPG books as frequently as I'd like, and they don't always have everything I want, so I turn to the internet about half the time.
6.) Mainly modules or homebrew stuff?
Both. Right now, SnowDog's running a straight Banewarrens campaign, and he's mentioned that he has a campaign log on Monte's boards. Our last campaign, which I ran, had a string of looted prepackaged modules in the frame of a homebrew world. Modules are nice because if they're quality, a prepackaged game has less prep time than homebrew.
7.) How long have you been playing and how old are you?
I'm twenty-seven and I've been playing on and off since nine years old.
8.) Who taught you to play?
I taught myself when my mother bought me the old Red Box Basic set for my birthday. She wasn't interested in learning anything about it; she just wanted me to read more. It worked.
