As someone who used NixOS as a daily driver for a few months, I also agree with not recommending NixOS.

In case you haven’t deciphered where the cut off points are:

• Cassette Beasts
• Pseudoregalia
• Return of the Obra Dinn
• Chants of Sennar
• Gloomwood

Here are my recommendations then:

CrossCode is a personal favorite of mine. An action RPG heavily inspired by retro games.

Library of Ruina is a great non-roguelike deckbuilder. Technically it’s a sequel, but it’s not necessary to know anything about Lobotomy Corporation to get the full enjoyment of its story. At most you can just look up LC’s true ending if you aren’t interested in brutally hard management sims.

Tactical Breach Wizards is a really intertesting mix between a turn-based tactical game and a puzzle game.

It actually is now. Both EndeavourOS and CachyOs have installers that set a good baseline to build off of.

That argument is stupid for anyone who understands how games utilize DRM and DLC. As long as DRM is not involved, there is literally nothing stopping you from getting the DLC from somewhere else. Things are slightly trickier with DRM, but not impossible.

If I’m remembering correctly, price parity only applies to keys sold off platform, rather than the game itself because they don’t profit from the keys being generated.

Not all competitive games require kernel level anti-cheat. Marvel Rivals, Overwatch, Valve’s games, and Halo all work under linux. It’s only a problem for people who want to play certain games like LoL, CoD, or Apex.
