Basically, GameRanger makes it quick and easy to play your friends online.
It has full lobby support for over 500 different games and demos (including Fallout Tactics, of course), without the hassles and headaches that usually happen with network connections (eg. routers & firewalls).
I'm really excited to be releasing it, and hope it helps boost the Fallout Tactics community by allowing people to play that were unable to until now due to problems with opening ports, etc. The more barriers that can be removed, the more likely the community will stay strong, as new users won't be put off.
