Why do people buy books? It's just paper and a bit of ink. You see cardboard, others see a very basic 3D printer with game creation tools or a bunch of $10 minigames/toys.
OT- If Toy Con Garage allows for a more official version of Bottleflip, I'll get the variety pack.
Wow....that's a zinger right there. Well said.
