VRChat is legitimately the best use of your headset. 
Only platform that fully utilizes FBT for multiple things and provides a programmer friendly way to make them, things like: RL style swimming, fighting games, physics games like brick breaking with your feet, RPG games where you stomp to bring up giant walls of earth, cars with real Newtonian physics, a clutch, brake and gas pedal and manual shifter (in vrchat!) DDR machines, dancerush machines, and many, many other things that utilize full body tracking. 
Udon is just where it's at. VRChat is the lucky platform to have the self sustaining userbase: without people to play your shit you are unmotivated, and making this stuff standalone isn't worth 40$ for a throwaway game. 
Making content in vrchat can be wildly popular and AAA level graphics. It can be profitable too. 
You literally don't have to talk to randoms to enjoy this game. Go to an event or go to play a game of peko peko battle or something. 
The only thing it can't do due to network limitations is pavlov-like games though lasertag and pool come close. 
Basically you need to write your own physics engine.
