See stop killing games.
I'm also in the process of trying to get my extended family to record something about their life for sort of an oral family history yoto card.
Also I thought that the physical design was poor. Because the figures just sit on top of the box, you cant move it around whilst playing it or the figures just fall off and the audio stops. It was very frustrating watching my kid try to use it in the car on a long journery.
Scrapped that and invested in Yoto player, its pretty much the same thing but its so much better in every way. The cards push into a slot and so dont fall out, it has an app which enables full control of the player which Tonies didnt, and you dont have to hit it to change tracks (which we found incredibly violent). Also there are some nice extras like being able to tap the nfc cards against your phone to set the content.
I would encourage any prospective TonieBox buyer to check out Yoto before taking the plunge.
