Some call it Terraria in space, and others Terraria without a soul. But it's neither. There are elements of 2D Minecraft, as there are in Terraria, but Terraria is more focused on bosses where Starbound is focused on crafting, building, gathering a crew, and exploring. The storyline is not exceptional, but it works. It's also not needed, and you can find mods to just get rid of it. It only serves to give you progression points that open new options. If you've never played, keep the story at least once. Then you can safely pass on it. The building just has had me playing forever. I have almost 1,000 on another platform, but I bought it here, too, so I could mod both copies different ways. I find it to be highly replayable and a lot of fun.
