Oh man, it’s been so long and I tried so many that I can’t possibly offer a certain answer… but a good candidate is JumpStart Preschool, which I (barely) remember playing on a Windows computer. Otherwise, it could have been The Busy World of Richard Scarry Busytown, Richard Scarry’s How Things Work in Busytown, Gus Goes to Cyberopolis, Fisher-Price Ready for School: Kindergarten, Fisher-Price Learning in Toyland, Fisher Price Great Adventures: Pirate Ship, or Nick Jr Play Math!
There are many more that I could name, like Oddballz, Pajama Sam in No Need to Hide When it’s Dark Outside, Ozzie’s World, Sesame Street: Numbers, Mr. Potato Head Activity Pack, Play-Doh Creations, and Candy Land Adventure, but I am less sure of those. Finally, there are those titles that I simply can’t find again. There was a point‐and‐click program that mainly took place in a spaceship, and another one where a character said ‘I brush my teeth before I go to bed every night!’, but I’ll be damned if I can find videos of those.
Off the top of my head, unambiguously neofascist video games include KZ Manager, Ethnic Cleansing, ZOG’s Nightmare (which the author made with an ‘FPS creator’), and the Angry Goy series. The market for explicitly neofascist video games is pretty small (at least for now), so, as you implied, it is rare for anybody to publish one.
