I've read a preview of this game months ago in one PC mag. Supposed to be a MMO, with millions of other planets you can discover. Too much for you to explore in one life. The other thing is that it has no goal, since it's just about evoultion and conquering later, but it's size makes it pointless to try to achieve anything other than spend some time, hopefully having fun.
I'm not sure how fun will the game or how big will the community be, but I find one much more important thing for the future gaming here. It's the world size, which will set the standards for all the MMOs, and later the other MP and SP games. So I find this game (and so do many other people) like a testing of a new engine, which will include stuff like DNK aswell, and huge open spaces, never seen anything like those before.
