Here are a few my six year old loves:
- Mario party
- Mario kart
- Bugsnax
- Kirby games. Many allow co-op so we can help with difficult parts but many games he's plowed through on his own with time.
- Minecraft in creative mode
- Minecraft legends of we sit and give strategic advice
- Minecraft dungeons if we play co-op
- Race with Ryan
- Pikuniku
- Any of the Lego games, especially when played co-op
- Catlateral damage or as he calls it 'kitty karate'
- New Super Lucky's tale
- Unpacking, although someone should be nearby to help with unrecognized items
- Katamari damacy, but the timer can make things stressful
- Rush: A Disney Pixar adventure
- Slime Rancher 2, this is another where the game is complex enough that an adult needs to by nearby to guide him on what the next task should be, remind him what critters like what food, etc.
He's just gotten big enough for VR games and really enjoys:
- Vacation simulator
- Tilt brush
- The Lab, except the secret shop part
We let him try a lot of games but keep an eye on what they do to his mood. There are games he can play that we don't allow simply because of how quickly they frustrated him. We also spend a lot of time talking about why games are difficult at all, and how challenges are a key part of what make things interesting.
