Lavender. It's a VR-compatible successor to Gmod running on the latest unity. Plays like VRChat but even better since it doesn't have the performance problems or bugs. I've been in the beta, and you can spawn over a thousand props without hitting your fps at all. World scripting isn't out yet, but the sole developer hasn't let me down with a feature yet. Same dev is also really easy to talk to in their discord. Not sure when it comes to early access, but it's worth wishlisting for the day it does. Should be around $20, which helps keep out the hackers that plague VRC.
