So I'm pretty sure everyone has walked by an eye biome already. I find it quite satisfying that something similar to this suggestion has been implemented into the game. As such it would really be redundant to be suggesting a suggestion that is already ingame. I won't be updating this topic [or any topics I have] anymore because I'm inactive, but once the game is release I do plan on making a mod for it, complete with the Planet and creatures itself. But if that plan fails, well I have better plans for it in the game industry. If I ever do pick this back up, I might be placing them on dA.
Only issue I see from this is that it ruins the ability to send coordinates to friends about 'this planet has X on it, lots of cool stuff'. Remove the spreading and make it into a just a potential world that spawns.
Ugh, like I said I won't be updating this suggestion anymore. I will keep the spread, because that's how I envision how it would be like in the game. That is how I will be modding it once I find it feasible to do so.
It may actually help if ya mention that in the OP. I seriously doubt anyone's gonna be looking at the last page first for information.
