I love Endless Sky, it’s honestly one of my favorite games! I have a pack of cool SciFi art that I found on Nexus and I’ve been slowly replacing the stock photos for my personal game. I’m also a sucker for TeeWorlds, it is delightfully infuriating and hillarious to play. I know that’s baby’s first FOSS games but I’m new to open source games. That’s why I want to hear your recommendations and see what are some other good ones out there.
Here’s my favourites:
Blob wars is a 2d platform/shooter that is great fun (great sound effects and hilariously excessive gore).
Warzone 2100 is an RTS with a “neoclassic” appeal (something that would have felt like “the future of RTS” back when you played Command&Conquer).
Battle of Wesnoth is a hex-grid strategy games with loads of mods and campaigns.
The Battle for Wesnoth is my all-time favorite FOSS. Can’t understate it.
