A very good Space Strategy RTS game unlike Ogame and others it is very Real time and you can track your fleets on a graph, you can colonize planets, mine for ores, wage war and join alliances. Very addicting and almost at the end of Open beta, the only bad thing is ticks are so long aprx. 1000 seconds but still less then the others I have seen best of all F2P no download at all you just need basic Java, Includes a good beginners guides and tutorial full of screenshots, Come join and maybe you can conqure the galaxy. rated a 10
