This was a thing that always kinda bugged me when I played Spore; unless it was an epic, rogue, or baby creature, the sizes really didn’t differ too much between creatures. I think it would be cool to see that change in Thrive, where the organisms have visible differences in size.
That makes me wonder…just how big/small could you make your organism? Would you be able to make an insect not even the size of your finger? Or maybe an herbivorous animal the size of some of the giant Sauropods that were around back in the age of the dinosaurs?
It would be cool if this had some sort of gameplay aspect as well, like for example maybe if you’re a really small animal you would be able to access smaller places that bigger creatures couldn’t normally reach, like a little burrow. Or maybe if you were a really big animal, predators would be less inclined to hunt your species unless they were around a similar size as them.
