I’m also not sure how well the contents translate to German. After all, Germany has not only compulsory education but the “allgemeine Schulpflicht” (i.e. compulsory school attendance), meaning homeschooling is, for the most part, strictly illegal (Switzerland and Austria have different rules, though).
The fact that Germany has such strict restrictions was a major factor in wanting to produce in a German edition! They need as much inspiration as they can get to change their system.
