As the developer of a MOD for SC2, I would like to present Risk Revolt to this community.
It is an adaptation of Risk into a 12 player RTS format.
Each turn is 45 seconds, players earn coin income for countries controlled and gain a card each time they conquer a city which can be traded for coins. Coins are used to buy more troops. There is navy and army.
There is a large commmunity of players on the Starcraft 2 arcade that enjoy this game. And due to SC2 multiplayer recently becoming free to play, if you enjoy Risk and the RTS genre, now is as good a time as any to try it out!
