Recently I got the game "The Logical Journey of the Zoombinis" for my kids to play on steam since I got young kids and I remember loving that game when I was younger.

The game is amazing, the way it combines fun, learning, and engaging kids without ever feeling like it's a lesson. Seriously my 5 year old now has a basic understanding of set theory because of it.

It feels like educational games peaked in the late 90's and early 2000's and everything since then has been a regression that spends too much time trying to explain things to students rather than letting them discover and explore for themselves.
