Wow... so far so very good.

Installed Mint 19 BETA (Cinnamon edition) yesterday. Setup all hardware (installed nvidia drivers etc.). Installed EVE Online the same way you would for ()ubuntu. Works like a charm. Installed Trackmania Nations from the newly created snap packages for it. Works perfectly. Saw a video for Realm Royale (Hi-Rez studios new alpha stage Battle Royale game), then saw it was available via lutris. Boom installed and works fine. Installed GIMP 2.10 via Flatpak, just works.

Going to have to distro-hop to something unstable soon before I actually get something productive done
