With the advent of tribes ascend although I'm not quite sure if any of you care or not-I'm attempting to revive the original tribes-if anyone's interested-here's a few links:
http://theexiled.pwnageservers.com/http://www.fileplanet.com/140246/140000/fileinfo/Starsiege:-Tribes-Full-Game/Tribes was the first game to introduce squad-based combat and full on mobility-although by today's standards the graphics are crap, the gameplay-lightening fast and still on par with today's games, its also easy to mod-been thinking about doing a doom mod for it-if I can ever get the time.
Like I said-anyone who's interested-here you go and please, feel free to shoot me a few PM's if you have any questions.
