Some examples / ideas:
- Sex / purity, of course. Could throw in the issue of modesty along with that.
- Swearing, off color jokes, etc.
- Different religions.
- Family issues.
I don't know. Those always seem to be big ones that come up in youth groups, but hey, this is new game. So whatever ideas you guys have, let me know! AND BRING MORE MEMBERS!!!! *shakes fist*
