We play in
www.nationalsocomleague.com, they have a COD4 PS3 league, but it is much smaller than gamebattles.
Quite honestley, I hope on the next Socom they include in game ladders / tournaments like they have stated that actually work.. hopefully clan only party system.. so I do not have to use another site...
Been playing Socom since month 1 of Socom 1, long before gamebattles, and I have never liked GB, and we never play on it seriously at all..
