I'd never have guessed it'd be the case, but the number of "educational" games has exploded since I was a kid, while I'm not sure the rate of new ones that are any good at educating (not proportion, actual count) is even as high as it was in the '90s. It's kind of amazing. It appears that, for some reason, the market's way bigger but being any good isn't a useful differentiator for the purposes of sorting out who gets money. I mean you expect that to be the case with ad-supported, but paid edutainment games are like that too. It's so weird, my kids have been around for the golden age of the App Store and beyond, and there's been vanishingly little in the way of good edutainment games that entire time. A few, but it's so very few.
