It was pretty good, Paper Mario The Origami King being my favorite game of the year.
Games like Ikenfell, No Straight Roads, Super Crush KO, and Streets of Rage 4 were also pretty nice. Crosscode's release on Switch if that counts.
New Horizons was underwhelming coming from New Leaf.
Conflicted with Age of Calamity so far, tho it is a fun game at least.
Some of my favorite releases of the year that aren't 2020 games were Halo 1-3 on PC, Super Mario 3D All-Stars, the Atelier Dusk DX releases of Ayesha and Escha & Logy, and The Wonderful 101.
