Mario Kart 8 Wave 4 Tracks
I haven't played Mario Kart for ages. Pretty much since I got the Steam Deck, I think.
OlliOlli World
I loved the first two OliOlli games. Played hours and hours of them on Vita and then again on Switch. They're the perfect auto-runner and, in many ways, share a lot of commonality with the decent Sonic games.
