For me, as someone who's not into esports-games, I just expect games to work on Linux now, and they nearly always do. The exception has been a couple of old or obscure titles that run fine in a virtual machine. I'm not running any fancy version of Linux, just Mint, and the only thing I do to get them to work, is install them on Steam. Proton is amazing.

If you are into esports-games, though, there's a risk that they'll require kernel-level anticheat, and Linux does not do that.
