Regarding the opened issue ([Implement Non-Linear Osmoregulation/Size-Related Costs · Issue #4432 · Revolutionary-Games/Thrive · GitHub](https://github.com/Revolutionary-Games/Thrive/issues/4432)) it says: > Note that this cost would probably be represented as its own thing in the “Organism Statistics” panel in the editor rather than just being a tweak of osmoregulation, as osmoregulation is its own thing. This feels a bit wrong to be for two reasons: - We already have a non-linear size cost implemented in auto-evo, so adding an extra non-linear cost on top of osmoregulation feels like auto-evo gets even farther from the gameplay reality, instead of being brought closer back together - I kind of dislike having two systems that basically do the same thing. Why shouldn’t we make osmoregulation non-linear? Though, I guess for max realism we would make osmoregulation diminish with size (thanks to less surface to volume ratio) and come up with another name for the non-linear size penalty. --- _[View the full topic](https://forum.revolutionarygamesstudio.com/t/size-osmoregulation/1043)._
