Lately I've been playing a game called Rising World. TimeTwist introduced me to it and while it is still early on in development it appears to really be a more realistic version of minecraft. My proposal would be to investigate adding a Rising World Server to the BiG environment if there is any interest in doing so.
While we wouldn't be able to link with our existing chat system, we would still be able to converse via Discord. Let me know your thoughts, and I'll look into it if there is enough interest.
