Most games work! Notably, if the game you're playing doesn't have an anti-cheat that's deeply tied to the kernel then there's a good chance it will work with Wine (or Steam Play's version of it) out of the box. The anti-cheats that are deeply tied to the Windows kernel are usually dumpster fires of remote code execution so I don't think there's much of a loss there.

Things I never liked - spending hours debugging WINE issues or browsing the wine compatibility website trying to get things to work to play a video game, which I'm already using to get away from doing tedious work.

These days, most games run fine out of the box with proton. As the parent comment stated, it's mostly games that rely on invasive anti-cheats that don't work. For example, PUBG, Due Process, Valorant, etc... aka competitive multiplayer games.

If one really wants to they can dual-boot with windows, but I've found the better option is to just play games that do run well on linux, like tf2, etc.

Having to use something like Steam (Internet based DRM) to play games effortlessly on Linux seems to beat the purpose. At that point I'd rather just have a separate Windows 10 install where all I do is just gaming.

You don't have to use Steam. I just use it as a one-stop shop for updates and launching. Some games work in native Linux and most of the rest work fine in plain Wine.

If you don't like Steam as a launcher then there's also Lutris and GOG.
