I'm not so sure about the "literally doesn't exist" part, schools have been buying educational video games for decades.
25 years ago I played educational games that look conceptually identical to the kind on supermathworld and mathbreakers. I built space stations, launched rockets, battled monsters, and even learned geography and critical reasoning skills to catch the elusive Carmen Sandiego.
Graphics and gaming capabilities were a bit different on the Apple IIe though :)
