I find them cool for kids as they breakdown historical myths in a fun way.
E.g. Dick Turpin the “hero” 18th century highwayman. I only knew him from the TV series. ( a bit like the Dukes of Hazzard with horse charges instead of a Dodge Charger). It also features a 18th Century aristocratic version of Boss Hogg.)
They also do a lot of museum puzzle game/guide books.
