I can't overstate my pleasure with this device. I use it every single day. So far, every single game I have tried to run on it works great. Elden Ring, Stellaris, Doom, Age Of Empires II, any game on Steam works that I have tried.
I use the touch pads for more mouse based games, and the controller for controller games. It works flawlessly.
I also have dozens of emulated games. Most work perfectly, some require a bit of finesse and a few emulated games I can't quite get to work. Specifically a few PS2 and Wii games. But nearly every game emulates perfectly and that's amazing.
I know the screen isn't 1080, but on such a small screen it really doesn't matter. If you haven't gotten one yet I highly recommend it.
