I'm usually a fan of open source games but rarely do they manage to be actually great. People like giving recommendations like Super Tux Kart that haven't aged well and don't play well. What are some open source games that are legitimately good that I've missed?
How do you run OpenRA? I've tried both flatpak and snap and it didn't work. It gets stuck on the first screen asking about downloading content but I cannot click anything.
Just don't use flatpak or snap. I'll bet anything that switching off flatpak/snap will solve all your issues. Just check the downloads page on the OpenRA site and find whatever works on your system.
The flatpak has been working for me on Linux Mint, although the flatpak didn’t work on Ubuntu proper. From what I understand the Mint devs do some extra tinkering to support flatpaks better than vanilla Ubuntu. Have you tried downloading the binary and running it from a terminal?
The Appimage also works well for me on my Ubuntu XFCE box.
