Need Help Picking Games for LAN Party

I have been tasked with setting up a school appropriate LAN party. I was hoping to get some advice for what would be a good group of games or mods for games that would be school appropriate(i.e. no blood, gore, sex, drugs, or other profanities). I am looking for mods for games like Halo or Counter strike that make them like paint ball with no blood. I am also looking for games that are good online/LAN multiplayer games that aren't FPS's.

Can you guys help?

not sure if it is the type of game you would like to play, and 360 (or any pc pad) controllers would be needed, but i Love Super Street Fighter 4: Arcade Edition lol

there is a cool Star Wars mod for Call of Duty 4

You could try Quak Live. And garrys mod is pretty good for Lan's.
