i dont know how
active they are since i haven't played them (there's no way my laptop could run most of these), but i do know of
feralheart unleashed [a remake of feralheart],
glasmar, and
draconia. wolfquest is still around if you can find anyone to play it with but as far as i can tell it,, runs worse than before its rewrite and doesn't really have anything new, so it's probably not much better than animal jam.
i've heard of some roblox games that may fill that niche. i think some of them are called "dragon adventures," "griffin's destiny," and,, i swore there was a third one but i can't remember it. i refuse to touch roblox with a 10ft pole </3
i have been trying to find a game since faunasphere shut down and haven't really found anything like those genres of mmos. feral was the closest and it shut down about as fast as it opened, but i've heard there was a group of people trying to create a rewrite? i don't know much more than that though.
edit; there was also a project to create a faunasphere rewrite called faunasphere sunrise but i'm not sure how that's going. it's definitely something i'd try to keep an eye on if you like animal mmos with more than just trading/dressing up!
