Now this is the way to make an educational board game: Equal emphasis on getting both the principles and the gameplay right. Enjoyable as learning may be on its own, an unbalanced or un-engaging game can take the fun out of what it's intended to help with.
I'm also impressed with the visual and typographic design of Entanglion's game components. I was surprised not to see a Kickstarter for a professionally-manufactured box set.
