Um, for one, a Day Of Defeat online type play would be much better in my opinion. If you dont play, I'll explain it...
You choose the position you want to be, sniper, infantry, heavy weapons, sargent or whatever, so basicly that incorporates actual teamplay into it. SO like a shotgunner, assualt rifler, sniper, etc... Medic room, pffffft who cares. Its suppose to be how many people you can take down before you die, so it shows true skill... And um Mr. Halo Addict Abes Son, in your profile you spelled SPARTAN wrong. Its SPARTAN, not SPARTEN, way to go smarty. SOme halo and gamer you are, once again pffffft
PS: SOrry if I'm offensive to you, you seem to not grasp the idea of online gaming mainly, most people enjoy seeing how well there skill gets them...
