Since this is a site for gaming as well as web development... I thought I'd mention I just found an amazing freeware "shooter" called BaboViolent 2. It's a purely multiplayer game with deathmatch/capture the flag games... it's a simple interface, top down view, but highly addicting and easy to get into. You've gotta check it out!
