The first in-app based game I see is the karaoke one, which is free to download and you pay for eaxh song. That’s reasonable, I’m just noting the mechanism is there.

Then a game like Senran Kagura, centered on boobs (lityeraly, the main gimmick is vibrations from “massages”) also came to the switch, and I can’t remember any IP of this kind up until now on a Nintendo console.

For better or worse, the current Nintendo is much more open and less risk averse than before.

You mean, except the two Senran Kagura games which have already been released for the 3DS?

Watching my kids (4 & 5) play monument valley is a joy. The game costs 5€ and is absolutely worth it.

What kind of research have you done on what's available?

I'm genuinely curious as to what's out there and who's working on things like this.

Right now from WiiU to Switch my impression has been that the entire platform is “kid first”. Online play is chat minimal with only some prescripted text. Friendly characters from the Mario universe with great games built around them like Mario Kart, Mario 3D World or Zelda.

With Zelda I like that my 9 year old is slowly working his way through things that are hard. He’s talking to friends at school about how to work through tougher parts or find secrets.

Probably the thing that I wish was available more than anything was an equivalent to Nintendo Power magazines. Being able to let them read, find secrets, learn about other games, etc from something where I don’t need to worry about parental controls or click to buys would be a relief.

I like giving them to opportunity to find ways through something that is hard but fun. I just don’t want to have to feel like I have to keep looking over their shoulder.

Is curating your kid's apps to only allow such games an option?

The app store is 99% low quality garbage. Sure, you can spend your time and effort searching out the 4-5 high quality gems that may exist and configuring the ipad but it's 10x easier just to buy a Nintendo game and call it a day. Nintendo's first party games are almost always very fun, always high quality, ad free, and always(?) kid friendly. When you buy, for example, a Zelda, Mario, or Kirby title you know exactly what you are going to get. Not all entertainment needs to be "educational" and we are talking about entertainment here.

Surely there are blogger parents who do the work to find decent games for kids, educational or otherwise?

Unfortunately that's a near non-sequitur. For example a "math game" may actually be a crappy button smashing experience that's made to look "educational" in the store. Etc.

As for good games with educational value, I'd point to obvious examples like Kerbal Space Program (makes 12 years old learn the math behind rocketry and orbital dynamics), Minecraft (can make kids learn to program), Zachtronics games like SpaceChem or Shenzhen I/O, and ultimately any narrative-heavy game as a good way for kids from non-English-speaking countries to learn English.

Yeah, basically anything in that category except perhaps for rote memorization of multiplication tables is better done by a human teacher and static quality educational materials.

"Kerbal Space Program (makes 12 years old learn the math behind rocketry and orbital dynamics),"

With a) MSc in physics b) two kids in school c) over 700 hours spent personally in Kerbal I disagree. It does not really teach math and claiming it does is delusional. However, it does give a pretty intuitive introduction into orbital dynamics. It's a fun game. And there's nothing wrong in that category! Fun and games are as important as learning, but these two categories are complementary. Pretending one is the other does not really help anyone.

It's confounding to confuse the two as a parent who has to consider how the kids spend their time (i.e how screen time is rationed). If my kids want to play Kerbal, it's rationed from the "digital games" category and not "educational". For me "educational and character building" category includes stuff like 3D modeling, playing and mixing music, creating stop motion animation, etc. The latter they can do as much as they like.

If you take a look at the community around KSP, you'll find plenty of kids learning math and physics to better understand what their spacecrafts are doing and how to make better ones.

Reminds me of how I learned trigonometry myself - I hated it at school, but learned it immediately - along with basic matrix/vector linear algebra - once I needed it to rotate stuff in a game I was writing.

This brings me to my core issue with edutainment - fake problems. Bite-sized issues designed to "teach" a kid a particular concept, which can be immediately recognized for what they are - school after school. Fake problems are not fun. Meaningful problems - those working within the context of a game world that stands on its own, like "wtf is ∆v, how does it work and how do I ballpark the amount of it in my rocket" - those are fun and motivating.
