VRChat is a free game where you can hang out, meet people, play some games from some worlds, or explore what some worlds the community have imported or made themselves. You don't even need VR to join so you won't be missing out on much!(Oooother than being able to pick 2 things up and doing some hand gestures)
Want to make your own models? You need a VRChat account, Blender, and Unity for that to work as models right now need to be at least 20,000 Tris or less, minus making weapons appear and such.
I find VRChat to be fun as I make my own models and animations for them. Though I'm not sharing a majority of them just yet. Other than that, it's nice to hang out with so many people on it(depending on how you meet people, public rooms can sometimes be a bit...bad).
>>6 Do it, I know a few VR DJs, was just at a brand new venue a friend made earlier and that was 40+. Making and optimising worlds is a tough chore but if you can pull it off and advertise well, shits great!
