Same here :)
My wife grabbed one of those games and did a map from time to time to chill out with coffee. It didn't take long until our daughter noticed my wife playing a game and she was sucked in very quickly even just by looking over her shoulder and shouting (right in her ear:P) ~ there, there you missed xxxx :)
They liked it so much, we've recently grabbed a book at local store which seems to be very similar to a simple "find object" game, but seems to be accompanied with a book with stories/narratives related to the objects.
It's been a busy xmas ans newyear's time, so it's still patiently sitting on the shelf for when we have a bit of free time, so I can't really say anything more, but we've took a brief look and it looks very promising!
This one I linked below is that one we got, it's obviously in Polish, but I guess there might be similar books in English or Japanese?
