WarGear is, essentially, playing games of Risk online. Games can go on in real time or even for days on end.

For those of you who haven't played Risk, the objective is to gain control of the whole board. Players start with a few random locales under their control, where they begin to ration troop placements, conquer neighboring territories, fortify existing ones, and ultimately eliminate the other players by taking over their territories.

With WarGear, players can even create boards with their own set of rules, restrictions, ect.
 
Feel free to post your names here to get some games going, and tell us about any experiences you've had while playing.
