So I downloaded The Endless Forest.
There is no chatting, no goals, nothing to collect, you are a  male deer -no genders- with a human face. Though you can make your deer look feminine like a girl.
And you run around in an endless forest in a constant multiplayer with other people.

The only actual goal is to grow up - you start as fawn - , get different coat and horn and mask variations, and make more deer characters.
It's very interesting though.

So far I've met a fawn, danced for a while, run around until I turned into a frog in a pond, lost my fawn buddy, found a couple older deer, found a pair of parents and run around for a while, discover new coat and horn patterns but they only last a few minutes since I'm a fawn, lost my parents, found them again, then mom had to go and I ran around with dad and found a new buddy with peacock markings, then my computer died and I lost them both, then I log back on and run around for 30 minutes, find dad and HES A GIRL AND SLEEPING WITH A GRAY MALE DEER AND IM JUST LIKE WTF.

I suggest it though.
I think it's cool and they have a group on dA and forums so you can still kind of chat with people.
