Well I'm not going to be able to come up with ten for 2017 or 2020s first 4 months.
I'll have to stretch to ports in order for this to look resonable.
I've put the games that I haven't got yet in bold.
2017
Night in the Woods
The Legend of Zelda: Breath of The Wild
Snipperclips
Fast RMX(Wii U remaster)
Super Bomberman R
Snake Pass
Wonder Boy and the Dragon's Trap Remake
Kamiko
Puyo Puyo Tetris Switch port? Does that count?
Mario Kart 8 Deluxe (Barely a new release)
2020
Dr Kawashima's Brain Training for Nintendo Switch
Two Point Hosital came to consoles
Samurai Shodown Reboot came to Switch, does that count?
Landgrisser 1 & 2 Remake
Vampire: The Masquerade - Coteries of New York
Mount and Blade 2 (I won't touch it untill it's far out of early access)
Silver Falls 3 Down Stars for the 3DS is the only game I've bought in 2020 that was released in 2020.
