I think a good idea to incorperate into the game would to have different sized planets. The only thing affected with this change would be the size of the gravity wells, ie. smaller planets smaller wells, larger planets larger wells. Also I think that asteroids need to have a reduced gravity well to make them harder to deffend. In reality I think it would be much harder to deffend an asteroid than a planter. I don't know if the devs are open to this idea or not. Any feedback?
