Pioneer Space Sim, it offers unlimited space exploration in a huge procedural generated universe. It's like a mix of KSP and No Man's Sky.

0 A.D., it has a gameplay like AOE with a theme of the 0 A.D. periods.

Xonotic, a fast-paced online FPS game, but it looks like the server don't have much players recently.

The Dark Mod brings you an experience of being a thief and sneaking through the darkness. It has a lot of community-made maps.

If you'd like, I have an open source-game called Dungeon Maze (https://github.com/raihankr/dungeon-maze). It's a maze solving game with 2d pixel graphics. It was made with vanilla HTML, CSS, and JS. Utilizing the HTML canvas, I didn't use any game engine library in the development.
