I suggest a good Mario Sports, like Tennis Open or DS Hoops 3 on 3. Good games to pop open and play around with!

aside what every yt video says, here are some sleepers: happy home designer (like a animal crossing the sims), dragon quest (rpg designed by akira toriyama), wario and gudetama (fun minigames that dont suck lol) gudetama have a kitchen development backstory

Sure ! - Kid Icarus uprising - Resident evil revelations - Monster hunter generations - Captain toad treasure tracker - new super mario bros. 2 - mario kart 7 - Zelda ocarina of time 3D - Zelda majora's mask 3D - Pokemon moon/sun - Mario 3D land - Donkey kong country

Nintendogs is a ton of fun!
