A lot of old games have become unplayable on modern hardware and operating systems. I wrote an article about how making games open source will keep them playable far into the future.
I also discuss how making games open source could be beneficial to developers and companies.
Feedback and constructive criticism are most welcome, and in keeping with the open source spirit, I will give you credit if I make any edits based on your feedback.
Not challenging, what good open source games do we have so far?
Super Tux Kart is actually great. Open Arena is just Quake 3 with original art. IMO Open Arena is criminally underrated
Shattered Pixel Dungeon is great, actively developed, and was only possible because the original Pixel Dungeon went OSS. !pixeldungeon@lemmy.world
Mindistry is a best in class game that is FOSS
Off the top of my head
Here are some that I’ve liked (haven’t played them in years though):
Barony is fun as hell. Engine is FOSS, but the default game assets require purchase.
Cataclysm: Dark Days Ahead and Dungeon Crawl Stone Soup are two examples off the top of my head. Traditional roguelikes are often open source.
