I really like that you can throw like any USB/Bluetooth/Dongle controllers lying around at it to play some nice couch coop/multiplayer games when friends are around (in docked mode on a big screen oc). Stick Fight The Game with up to 4 players, Gang Beasts with up to 8, Nidhogg I and II for a tournament.
It’s more than a gaming device, has a linux desktop (I used it as multitrack recorder with a Behringer X32), you can use it docked as a console. Good look and feel, (almost) your whole steam library otg and you support Valve in improving proton which helps linux gamers.
edit: you can install heroic launcher too and access the epic games store
Thanks a ton! What a great list!
