Why GameConfig, well it seemed to be that me and my friends were always hunting for TCP/UDP game port numbers before we could start a game (We had reset a router, reinstalled a game, was at a LAN party, etc, etc). There didnt seem to be one place to go for this game configuration info, that was:- up to date and indepth, hence this site. Currently the TCP/UDP ports given within each game details are the max needed, you may get your game running with less open (eg you're not running a server).
