Seems like you have played with a lot of d'bags in your time, not everyone one is out just for themselves you know.
The world of xbox, as far as I'm concerned, is a world of lone wolves tied together by a common game. I do my part to help a team cause when its needed but I often find that its only the one guy making that crucial push or dropping med packs to his team. Other than that its, "Oh I can get kills here or XP there."
Even "team based" games like Bad Company 2 are full of snipers lining the map doing whatever they want. I've got good by the pressures formed from this hinderance. Its also why I have many of the views I do.
Only when I'm plaing with my friends, most ex military, do I truely see the potential of teamwork as we work like one unit. Unforetunatley, due to the cartoonyness of Brink, I'll be doing this one all but alone. I got hope for the game, I really do, or I would have run a long time ago.
