Not all of your games will work on linux but thats not a linux problem but a game developer fault. You cant do anything about that by switching to a different distro. Especially those fps games with intrusive kernel level anti cheat will never be supported. Go to protondb and look up all the games that you need and see what works. I personally made the switch and simply stopped playing those that doesn't as for each that doesnt work theres a dozen of them that does. Proton really is a godsend.

And installing anything on linux isnt such voodoo magic that you have to worry about. For example flatpak lets you do "flatpak install something" and everything is done without you opening your browser and downloading stuff, going through a lengthy annoying installer. If you want to completely avoid opening terminal then some have appstore like discover on nobara which is simply microsoft store but actually usable. For those that arent on repo you can still download a package and install like windows. Linux really isnt that hard and i would even say its easier than windows if you get one of stable ready to run distros that simply works without any tweaking. It took you years to get used to windows so everything different looks difficult when it just takes a month or 2 to get used to it. If you dont want to make the jump then dual boot it and use it for a while till youre ready to remove windows completely.
