>>39198347Hollow Knight for sure. Only $15 but more soul and content than the last three generations of Pokemon games put together. Some other baseline essentials/recommendations:
>Mario Odyssey>Breath of the Wild>Splatoon 2 (if you don't mind a lack of Splatfests since the last one is coming up)>Mario Maker 2>Into the BreachAnd of course any ports you missed from the Wii U era. Pokken, Mario Kart, etc.
