I had a surprising amount of fun with the Dragon Quest games, DQ Builder I/II and Treasure Hunters. Squeaky clean polish and very focused, nearly arcade-like gameplay. Don't forget the various Marios and Kirby Forgotten Land.

Cadence of Hyrule is a bit of a weird departure but very fun and replayable with a kickass track. You can get the Binding of Isaac physically, as well as the Ori collection which is incredible and Stardew Valley. Moonligher is a bit repetitive but that can be good comfort. Celeste, if you've never played it, is potentially life changing if you struggle with perfectionism and/or anxiety.

For a very obscure digital game, Chasm was an amazing randomized full-length metroidvania.
