I know Schema already tried spherical planets. Yes, other games will have it, but they are likely not using the Schine engine, and don\'t have all the same challenges as Starmade\'s universe. Each project has their own problems and solutions. Also, would proformance drop significantly if Schema did make spherical planets? I think it\'d be awesome if someone could make a mod for it, and if it works, then they could show Schema. But since Schema had tried it and posted the difficulties in the news, I don\'t see it coming too soon.
Still, it looks like a cool game! I still prefer Starmade, however, though it will be interesting to watch and see how that one progresses.
