As long you don't play multiplayer like cod, cs, forntinte. Linux is a gaming system. Yes sometimes you need to apply fixes from protondb or wait until the game starts for a minute, but it usually just works. At least if you are using steam.
You can run the epic games launcher through steam though. But you should install it with lutris. Or just use the hero launcher (which doesn't support cloud game saves yet)
If you look at it the arm is cut smaller than the trunk. So it looks a lot smaller than it actually was. And probably there was a branch where the thumb is, because even with the 30 cm more it ain't enough for that thumb.
I am kind of a scientist myself.
