I don't see much I would actually want to use yet but I do think mods will be the thing that keeps people coming back to this game for a long time. If I could get a mod that would just put more grass and other details like that onto some planets so they aren't so barren I would absolutely use it. I would also get a higher res texture mod and maybe something that puts more sentient aliens into the world even if they aren't doing anything but walking around.
