Gothic Trilogy? I know they are old, but damn those games would be great for on the go play. And the Switch IMO is perfect for older western RPGs in general.
Gothics are not exactly controller friendly, they would have to redo lot of stuff, and Piranha Bytes maxed at 30 people, IIRC.
But remakes in UE4 or something like that...oh, I would love to see that.
