a whole bunch of us play together on uni 1 under the alliance Asylum. Its a free site and game, you dont need any special video card to play it. The gist is each person owns a planet and builds it up. Others may attack you for your resources to help them bet bigger, you can do the same. The first two weeks is a pain in the *** because you grow in small bounds, but once you're over the hump it seems to fly.
Alliances can also create allies with other alliances, or on the other scope, declare war. Then those two alliances try to hit each other as much as possible making their enemy go down in points.
If you give it the time it needs to get over that hump I mentioned, it is truely a fun game to play. you get swept up in it, but its not agame you have to stay at your computer for every minute while youplay. Great for parents who dont have the time to sit endlessly at the keyboard.
