Yeah, I made an account on Codeberg recently, but haven't actually put anything up there yet. I'm kind of leaning towards self-hosting at this point though. I feel like I've just had one too many "free" services that have spoiled on me. Honestly, GitHub's convenience and community was the biggest draw for me. I have a server with a bunch of my small private projects on, but setting up and updating web software is a pain I didn't want to do. :p
Realistically I don't expect many (if any) contributors on VE though. Currently only the code is OSS as I haven't figured out what to do with the assets. It's also contains very little "engine" code, and the parts I do have is simplified and tightly integrated with the game. So to me at least it feels very different from the open source libraries I've worked on in the past. Honestly my main reason for doing it is because I keep running it on like Haiku OS, OpenBSD, or cheap handhelds and figured maybe a small handful of people would appreciate the ability to do that on their own. :)
