I’m looking for recommendations for my Linux setup. But shattered pixel dungeon is amazing on android
Cortex Command Community Edition
Tremulous is a free and open source asymmetric team-based first-person shooter with real-time strategy elements. The game features two opposing teams: humans and aliens. Each team must attack the enemy’s base and team members while defending their own base. https://tremulous.net/
Currently downloading but is it still active? Is there still a player base?
Open source game based on Transportation Tycoon Deluxe.
Not a very original answer, but I still enjoy The Battle for Wesnoth after many years.
I’m surprised hardly anyone else has mentioned Wesnoth yet. I last played it over a decade ago, so I’m not sure if it’s still as well-known now as it used to be, but it’s one of the highest-quality open-source games out there.
It’s a turn-based fantasy strategy game that feels like a combination of Advance Wars, Fire Emblem, and D&D. And I suppose it was a lot more unique back in the 2000’s when there weren’t a dozen indie games out there that fit the same description.
Mindustry is neat if you like tower defenses and factory/automation games.
[edit] Though this isn’t exactly a game, I thought I’d mention it: The Powder Toy. Really fun physics-ish sandbox game if you like just playing around with little particles or making electronics or nuclear powered fireworks shows, etc.
