After reading the “issues” discussion from w weeks ago, this is just an idea at this point. The simplemobiletools fork was a mock up for something that sounds like its very much in the planning/ideas stage. you can also go to fossify.org to see another mock up that does nothing right now. You could message one of them, but I think maybe its some MIT software team / group & their just tossing ideas around for a foss hub of sorts.
I’m not sure I understand - what would you call Banjo-Kazooie? Or even Super Mario 64? What do you mean by “3d platformer”? Like “open world” kinda game?
