The "hit a button to rotate and reveal a hole" feature for Wonka is decent but not a great "toy" like they want it to be. I agree that the MM castle is darn awesome and I can't really find any other toy that can top that to current date; the feeling to lower the drawbridge, raise the gate and then enter and destroy castle is really fun.
I find the newer games kind of lacking in imagination, its not really any new inventions going on, mostly rehashing old mechanisms. I give Dialed In the credit for using a mobile phone in the game, but obviously that wasn't even possible in the 80/90's.
