my brother played few years ago. it sucks because it has no goal, if i remember correctly. you just grow stronger and stronger and the others do as well. but you can not be destroyed, because you can not be captured or annihilated. it is just a waste of time. you have to be the first to play to be strongest. do not go for it.
you dont even have a map. just an infinite ammount of planets sorted in systems and galaxies. the battles are like: 350 heavy fighters and 30 battleships against 450 heavy fighters and 45 battleships - you lose.
