Also, interesting to see the Hello Kitty theme mentioned. When I was at the ICEi show, there actually was a machine with a Hello Kitty-style theme! I’m not sure if, it was the real Hello Kitty brand, but it looked pretty close.
When I was last in Japan, I was amazed to see gaming sections for little kids in some of the amusement arcades and pachinko casinos. The area was of kids and mums putting coins in, and all the machines were about 4 feet high, with tiny little stools for the kids to sit at!
So as to not go completely off the theme of the thread, for my suggestion, I’d go for Mr Bean slot…
