@Moon @denza252 yeah maybe bc stats. but honestly youll be throwing out all of chao gardens core mechanics to use pokemon mechanics anyways, assuming you have more than one species.
and for an RPG, youre bringing the party mons with you and getting stat growth through battle, so whats the point of keeping them in the garden if youre not using them?
unless if you remove the RPG, garden only and you can get food for them from something else, then battle other players? idk.

breeding in general is an odd mechanic, idk how you balance it, maybe give mons a lifespan and require players to breed to keep them around? but babies will start at level 1 and have to regrind them again, annoying and unfun. SMT fusion fixes this by making the offspring be different and potentially more powerful while inheriting previous abilities.
