http://www.stellar-realms.com/main.aspI have been playing this game off and on since round 3/4. Its still considered beta , its free, there is no graphics to speak of but its an addictive game simplistic game, basically a turn runs ever 20 mins, you reasearch stuff, build out your planet, create alliances.
Whats fun about it is its a small community with a lot of returning players. (41 right now) so you arent just a number in a 2000 person game.
try it out , i told them i would send out the word.
