FleetCOMM : Operation Vigrior is a Kickstarter indie game worth checking out. It’s a real-time strategy game introducing a novel gameplay mechanic. Instead of fumbling over disorganized blobs of units, the player controls a synchronized squad of ships.
They’ve been very supportive of Linux game development; they already have a Linux64 build out on Desura. The complete game can be obtained with a $10 Kickstarter pledge. For $15 you get the game and all DLC, expansions, future editions, etc. forever.
