It's a flash based MMO that I was introduced to at PAX and have found I enjoy it. A rough summary is your a scientist raising Fauna (aka Alien creatures) to research this alien land. You can breed them and create aliens with useful or rare traits, design your own "faunasphere" where your fauna live, etc.
It is free to play, but for certain perks you have to pay.
I've been having fun without paying for it. If anyone is interested, the link is:
