The 6 month stretch between September 20, 2019 & March 20, 2020 was also pretty nuts and very targeted towards handheld gamers.
Nintendo Switch Lite (handheld only model)
The Legend of Zelda: Link’s Awakening (while 2D Zelda started on consoles, it has mostly been a handheld series since 3D Zelda started)
Dragon Quest XI S (one of the biggest 3rd party franchises in handheld-centric Japan)
Ring Fit Adventure
Luigi’s Mansion 3 (series started on consoles but had a major breakout on 3DS)
Pokémon Sword/Shield (undisputed king of handheld franchises)
Animal Crossing: New Horizons (no 2 handheld franchise)
With the exception of Ring Fit, late 2019/early 2020 was very focused on getting handheld gamers to migrate to Switch.
