Speaking of Linux gaming, a long long time ago I wanted to play Path of Exile, but I only had a Linux laptop running Mint. That machine was too underpowered to run PoE and Mint's Cinnamon at the same time. After significant twiddling, I managed to configure and run an X session directly for the PoE executable under WINE. No DE or WM, just the executable running under WINE. I played PoE (on lowest settings) for quite some time on my humble machine using that setup.
