Nintendo Switch

Mario Kart 8 has an auto acceleration and steering assist mode that works great for the kiddos. My son was 5 when he started playing it and still loves it a year later. He just now is getting good at wandering around in Odyssey but avoids enemies.

Never tried it but there is a Paw Patrol game for Switch.

Maybe some of the Lego games as well? I know they have co op.

Mario Kart, auto assist mode is brilliant. My son started on this and it really got him into other games (currently playing paper Mario with me doing the battles and reading). The game is also huge with the expansion pass as well. Had my switch since day 1 with Mario Kart and still play it!

Coop with my son was a huge benefit on the switch with those little controllers turned on their side. We started out around that time with Mario Odyssey where my he played as Cappy with its simplified controls and I moved us through the game as Mario. We also played Captain Toad Treasure Tracker because the controls were pretty simple and most of the time he could just practice running around, but there are definitely times you need both players to contribute and I’d end up “borrowing” his controller to get through things. As he got more comfortable moving and jumping, he played more Lego games on his own.

As a general rule for me, anything you can play with a single detached controller on its side was a good candidate because it meant the controls were generally simpler for a kid (or less experienced gamer in general) to manage.

LEGO games and Minecraft (on Peaceful difficulty) would be pretty good I imagine.

I can’t recc any myself, but here you go!

Switch games for four year olds

Yeah I might investigate a few of the Lego games. They seem to have decent sale reductions too

Go 2d first! Can't do better than the first 3 Marios, DK Country, Super Mario World, Kirby, etc.
