15th Birthday

Among a few ppl that have posted here, I am planning now for a party that is in July. I am inviting guys and girls but, most of my friends are sorta a tough crowd. Most will participate in games but some are just not the very outgoing type. If anybody has a couple of games or activities for teens, not to "intimate" as other ones I have read, lol, could you guys help me? I have tried games before like Truth and Dare, Twister, and other games, but I have no ideas left. Thanx. Oh ya, I also love giving ppl other things, lol, so I am hoping to make party favors, but I don`t know what to get. A few ppl don`t eat candy and there`s both girls and guys sooo...... If you can help that would be great.
