There’s a library for Matrix integration with Godot. Some FediJam projects have used it to experiment with the idea of federated gaming. Imo federation has most of its implementation potential in a VR-chat-esque game. There’s even a project in extremely early development that is exploring that concept on GitHub.

But it’s always good to think outside the box of what’s possible, instead of just emulating what already exists. Federation could eventually open up new possibilities in terms of game mechanics. :>
