I wanted to be more descriptive in the title, but I couldn't do this game justice with only a few words. This game, while needs a lot of work to make it deeper and whatnot, is amazing. From the website: "Dyson is an ambient real-time strategy game with abstract visuals. Remotely command semi-autonomous self-replicating mining machines to take over an entire asteroid belt."
Basically, you start out on an asteroid, with one tree and 20 seeds. Trees make seeds and seeds grow trees. Seeds can be sent to other asteroids, where they can take over and grow a trees. There are other species that are spreading through out the asteroid belt, and so when competing for asteroids, your seeds work as soldiers, killing other seeds. Finally, every asteroid has varying percentages of 3 values; vitality, strength, and speed, and any seeds grown on an asteroid inherit these 3 values.
But enough explanation, to really understand the amazingness of this game, just download and play it! Here's the website: http://www.dyson-game.com/
