Pretty sure i met you today. You see... back in the day this was considered a sandbox of an animal game, so what you did is pretty much up to you.
Many people use it as a 3D chat. Others gather friends and play animal thing.. act out fantasies from their head, or just download maps & mods for something to do.
Personally, In 2016 i was injured and couldn't create 3D things IRL & was like "What was that game from the old days?" found my way here, crafted things in digital 3D, added textures & scripts & low & behold, could run around in a digital world of my own making. Now i just make weird videos & stuff.
So try a few things, find what makes you happy. And if you don't like it, find a new thing to try.
