NoX is a pretty old game I played when I was a kid. Great singleplayer and multiplayer, even tho I just recently tried multiplayer on a LAN once. It was really, really fun!
You can play as Sorcerer, Conjurer or warrior.
The sorcerer has a shitload of spells, 20+ atleast.
The Conjurer also has a shitload of spells, but more healing, cure and stuff like that. Not as much offense as the sorcerer.
The warrior just bashes the crap out of people, also he has a few spells.
Anyways, it's a pvp game. I've only tried deathmatch, you get thrown in an arena. (There's loads of arenas/maps) and you kill eachother! HURR
Here's a video of the pvp, but that looks like 1v1.http://www.youtube.com/watch?v=KGbJvbDMEf8
