You know what the Savannah/Dry Grassland planets need? Their own unique Mini-Biome! I did a lot of thinking on what could be added, and I thought "we have giant mushroom, we have giant flowers, how about Giant grass? The giant grass biome would consist of tightly packed grass blade "trees" and a dry dirt surface . The terrain would have scattered boulders and giant anthills (perhaps with giant ants? ) There would be giant ladybugs wondering around the surface, and they'd be in a procedurally chosen color. Just an idea, but I hope you guys consider it!
