Linux for gaming

I want to pick an open-source replacement for Microsoft Windows (a linux system tuned for playing pc games). Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - Bazzite: Bazzite is a free Linux operating system for PCs, built on Fedora, that you install in place of Windows or another system. It is aimed at people who want a Linux desktop that works well for gaming, including on Steam Deck-style handhelds and living-room PCs. [Advanced setup (An operating system: installing it means replacing or sitting alongside your computer or phone's current system, which is more than installing an app.); Linux; replaces fully; Apache-2.0; https://github.com/ublue-os/bazzite] - ChimeraOS: ChimeraOS is a version of Linux (a free computer operating system) that turns a regular PC into a game console, with a controller-friendly screen for starting games. It is meant for people who want to play PC games without using Windows. [Easy setup; Linux; replaces fully; MIT; https://github.com/ChimeraOS/chimeraos] - CachyOS: CachyOS is a free Linux operating system for computers, built on Arch Linux and tuned to run faster. It is aimed at people who want a speedy desktop with an easy installer and a choice of desktop environments. [Advanced setup (An operating system: installing it means replacing or sitting alongside your computer or phone's current system, which is more than installing an app.); Linux; replaces partly; GPL-3.0; https://cachyos.org] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/distros-gaming.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/distros-gaming.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
