Hey, I like how creatures get scaled randomly to various sizes. I didn't think it was possible until I read it in your description.
Could their size possibly be tied to their level? High level creatures be bigger while low level are small?

Could make hunting and taming missions fairly exciting since you could estimate level by their size. When people panic and see a huge Megalodon and realize instantly that it is VERY dangerous.

(there may have to be limits so when people raise difficulty to the really high +34 or +50; the dinos won't be 10x bigger. lol.)
Maybe have adult dinos start out at 25% size at level 1 and grow to 100% at level 150. After that they grow 1% for every 10 levels. So a level 50 dino would be 50% of normal size, a level 100 dino would be 75% of normal. If the difficulty is raised, then for example, a level 300 dino would be 115% of normal or 15% bigger. A level 900 would be 175% of normal or 75% bigger.

Alternatively, the sizing could be 50% at level 1 and 100% at level 100. THEN switch to leveling 1% per 10 levels.
A level 120 dino would be 102% size.
A level 150 would be 105%.
A level 240 would be 124%.
A level 360 would be 136%.
A level 900 would be 190%.
A level 1080 would be 198%. (I play with difficulty 34 so dinos can spawn at this level)

So past level 100, their growth slows way down.

Maybe damage and health could scale up with size on all wild dinos. But speed should cap at level 150 on wild dinos.

Just the idea of going out hunting, and looking for smaller dinos to hunt to have easier kills or finding the biggest bestie to tame.
Or that sudden pit-of-the-stomach-panic when you see something just insanely huge.

I realize this makes for awesome scaling at normal 1-150 level difficulty but once the difficulty goes up the dinos get huge. Personally, I am okay with this. But for realism, it may not fit. Then again, if this could be a standalone that works with your mod, I doubt many players playing with the added realism are looking for dinos more than level 150.

It is just an idea and it could probably use allot of tweaks. But maybe it is something that is possible?

I run two private servers and one uses all of your mods as well as a couple of other mods. I also double the dino spawns to make things more dangerous. lol. Anyway, more or less wondering if scaling with levels is possible.

Thanks for your time!
