First of all, NECROOOOOOOOOOOO
I doubt this would happen. Starmades planets could be really nice and not rely on ditching blocks. Might also add that implementing true voxels like SE would be a silly difficult task and really ruin the feel of the game imo.
Starmade isn't exactly a normal space sim. We already have blocky everything, if anything, adding voxel based planets would ruin that.
Lots of games are coming out with "Full scale" realistic planets. adding another game that does that into the mix would be a bad thing. We need something to set them apart, and IMO, the way to do that is to absolutely nail the blocky planets concept.
Minecraft, Skyrim, Fallouts, source based games, Arma, GTA games, Cities skylines, ETS2, KSP, SoaSE:R and literally anything on this list
