I am hoping the EU and Blue States does a funding program to make open-source and federated projects more user-friendly. There is far too many proprietary ecosystems that will turncoat within years. We need alternatives that are approachable and easy for people to transfer their lives into.

There is a conversion of Wolfenstein 3D for the ZDOOM. Best way to play the game if you want mouselook and other nice things.
