The only one I found and use to follow during each worldwide events is still the Oliver&Spike by RockPocketGames (and made with Unity).
Other games aren’t for kids or just not interesting at all…
Such disappointment here, the game industry is getting WEIRD
Do I am wrong with it?
Please let me know 
Mario Kart, Mario World, Donkey Kong… Sonic… You can rely on the classics 
Well but what about the PS4? …
Those are usual Nintendo license anyway, right?..
Everything turn for adult on PS4… It could be a tombraider-like colored without blood/kill, or a The Division-like with more colors and no blood/kill too.
Kind of stuff…
So boring… It seems only the smartphones field do some progress on gameplay, and new content for your players.
I also think adults need more games with less realistic and blood content…
There are also wonderfull game on Nintendo 3DS like Fantasy life, kid of RPG for kids…
What are they waiting for to create such stuff for next gen console?
pfff…
Checkout our first production XnO - 3D Action Adventure Game available on iTunes, Google Play and kindle. Its physics based with non-violent gameplay.
If your kid isn’t interested in games, perhaps he knows more about life than you do.
I’d rather take my kids to a football or baseball school, or park and play with them, than buy games for them.
No offence, so therefore you cannot be offended.
P.S. What happened to Japan? Last year I was there, there is still plenty of parks and football pitches.
No worry, my son do spend more time outside to play with his friend than inside with his console.
About Japan that is not new, of course all kids do play outside, but that is not new the game market in Japan is the most fruity one in the world.
I am sure of that 10% of the Japanese games won’t be released over sea.
All kids here own a Nintendo 3DS or similar console.
Now the main subject is more about the market field of the next Gen console.
I wish the US had the kind of parks, rail, and trams for kids and grown-ups to enjoy that Japan and Europe does.
That’s why the game industry and US television is getting ‘weird’: they are all out to shock teenage boys into buying the newest gross-out games not thinking they teenage boys have minds too. Eventually the technology will cease to amaze them and they’ll realize: gross and offensive is just gross and offensive.
I think there is going to be a lot of opportunities for indies making kids games. Not just games, but educational interactive stories.
You should teach them how to use Unity
