The first party nintendo series are worth checking out across the board; Mario Odyssey, Zeld 1&2, Metroid Dread, Smash Ultimate, Fire Emblem 3h, etc. etc. *edit: except pokemon, those ones are trash. Play Casette Beasts instead.

Indie titles like Hollow Knight, Stardew Valley, Celeste, and Gungeon I end up liking more than their PC versions since you can lounge in bed and play them.

Skyrim, Dark Souls really don't need me to sell them, pick em up if you haven't played them before, or just want to play them again. Wondeful 101, Astral Chain and Bayonetta 1 & 2 are fun.

I like Warframe, so I'll plug that too, even though you're probably not going to want to play it undocked since it's an online thing.
