Looking for games Linux, i3 2100, 1.8 GB RAM

[Tianshee]

Hey, I'm looking for games I can play, my specs:
Ubuntu 16.04
i3 2100 (Integrated graphics)
1.8 GB RAM

I can play Counter-Strike: Source with 90 fps on minimal settings or 30-40 at okaish settings. Can play Garry's Mod with some freezes, but playable in single player.

I can also play optimized 2D games like Janosik. I'm looking what else I can play. I thought trying Age of Empires II, but in steam old version without DLCs costs as much as new version with all dlcs, and that's expensive.

Best if game requires ~512 RAM, some games that I met requirements doesn't run for some reason, even if they're made for linux. I can't use proton, it doesn't run here.

Preferably free games, but I guess cheap ones can work too, especially if they're very replayable so I can replay them later when I come back to my main PC.
