don't you have to pay for that? github is free at least, and it does only upload changed bits. there's some light documentation for the unity plugin on https://github.com/github-for-unity/Unity/blob/master/docs/using/quick-guide.md . Looking at the built-in unity collab documentation, their 'publish' is git's 'commit and push' essentially.

Yeah, that's apparently what Sports Bar VR does, fixes the bridge to the table on trigger. I've never played it, but that's apparently the only other existing billiards sim in VR.
