I'm 18, so I think I qualify for answering.
- what brought you into D&D/d20/P&P role-playing?
Well, let's see... I must have about 9 years old when I first began with role-playing. One of my friends had bought a swedish version of D&D (although I believe that the only resemblance between those two games is the name). I still don't know why he bought it in the first place, but it might have something to do with the fact that his father used to read Lord of the Rings to him as bedtime stories when he was (even) younger.
Anyway, that's how we ended up playing RPG's, and even though it was a horribly lousy ruleset (and campaign world) we kept on "playing" it for many years. It was first after the first Badur's Gate game shipped that our eyes caught AD&D. From there it was quite a natural step into d20 when WotC released D&D 3rd Ed.
- Do you find it difficult to find gamers your age? Do you game with people typically 10 years (or more) older than you, or is it easy to find gamers your age?
No. I don't know why, but even when I briefly lived in Denmark I had no trouble finding a gaming group (it was actually too easy there, I had to choose between different games and groups since I couldn't attend to them all).
However, I'm finding it harder to find someone mature to role-play with, opposed to roll-playing. And unfortunatly the members of my current group are getting less spare time to play (and somehow I now got more time). So the poblem isn't finding people to play with, but finding dedicated rolepayers. I guess I'll soon have to "educate" some of my friends..
- what are your peers into?
The ones in my group all got two common interests: RPG's and, to some degree or less, computers. Not so much computer games (I'm probably the one who plays the most) as Linux, programming and that sort of stuff.
All of us have at some point been proud geeks, but now ome of us are not as geeky as we used to be (guess that's part of groing up. Sigh. I miss the geekier days).
Oherwise we got quite diverse interests.
Oh, and by the way, I've been part of EN World since it was called Eric Noah's 3rd Edition News, so don't say there aren't any young people here.
