Dear Esther: Landmark Edition
I am mostly confident that all of those are either self published or published via what was at least at the time of original release of the game, a fairly small indie publisher.
EZ and EZ2 are technically mods for HL2 but they are pretty darn good and then quite good, respectively.
Dear Esther and MINERVA are also HL2 mods.
Squad is basically the old Project Reality mod for Battlefield 2, but made in Unreal Engine by at least originally about 75% of the old PR mod team.
Anyway, I tried to pick some games that are indie, but are not as well known, largely due to not being cutesy.






























If you want a Debian based Linux distro that is gaming focused, I would suggest to you either:
PopOS!
https://system76.com/pop/
Made by System76, who also actually make their own hardware as well, pre-built pcs, etc, and also successfully lobbied at least Colorado to not have a law that mandates age verification built into OS’s…
PopOS! Is essentially Ubuntu but less shitty, and is also making their own Desktop Environment COSMIC, that is basically an attempt at ‘GNOME, but better.’
There is also PikaOS.

PikaOS is basically to Debian as Nobara is to Fedora: Its the base OS, but with a suite of cutting edge/bleeding edge optimizations geared toward improving gaming performance.
