I mentioned this on page 2 (but it's gone largely ignored): An entire industry grew and survived basically by "cloning and reskinning". That industry was PINBALL. In 1947, "Humpty Dumpty" was the first pinball machine with electro-mechanical flippers. From then on, flipper pinball became the preferred format for this kind of amusement device and the industry supported dozens (if not hundreds) of different manufacturers. Each pinball game, from the 40's on to current day has been nothing more than a re-skin, with repositioning of the ramps, bumpers, etc into different configurations and "rules". There has been some innovation but it's been very gradual. An entire industry survived for over 50 years with one single genre of game. Competition is good, as it forces the talented few to innovate. Put out something "remarkable" and people will notice it above the rest.
