I don't think I've ever met a poly guy who isn't into either video games or board games or some other nerdyness. I've tried. And failed. lol Most of the poly women I've met have also been into that kink of stuff as well. I don't enjoy it and can barely tolerate hearing about it for more than a few minutes a day, so it has put a serious damper on my ability to socialize with most of the poly people here (Portland-ish), too.
On the other hand, I know a LOT of poly people who would pick camping over a hotel and enjoy the outdoors (whether it be hiking, fishing, hunting, biking, or whatever).
