0 A.D., an Open-Source Strategy Game
I love RTSs. Total Annihilation (TA) was an early favourite.SpringRTS is an open source game engine that improved beyond TA and actually had UI features that Supreme Commander has drawn inspiration from.The multilayer is epic, its totally LUA scriptable. People have re-purposed that engine for all manor of weird RTS type games. I sincerely hope this project is going to use that battle hardened, cross platform, actively developed, open source RTS engine rather than roll their own.http://springrts.com/wiki/Games
