yes i have tried polytoria, not for me
roblox sucks balls and i want to play something like old roblox, kinda like polytoria too but more like roblox, like that it has its own marketplace and stuff, not just the old roblox client. I want to be able to play with my windows friends btw, so either cross platform or in a web browser
It’s not a Minecraft clone, there are FPS games implemented with it, base-builders, etc. I didn’t look into it in detail, just thought that there is a chance it it could fit your needs.
Happy hunting!
