When I was a kid, I remember I would write letters to Sega all the time. One time, I came up with this concept - for a Sonic toy. A remote-controlled car, shaped like Sonic. The classic "spinning Sonic legs" would be the two wheels, with a wheel on his tail and a wheel protruding from his stomach to give him balance. It would control like... I guess a Katamari would be the best description. Or Virtual On. You'd get one stick per for each of the two wheels (legs).
I drew up diagrams for Sonic, Tails, and Knuckles. Each character had their own personalized remote control; for instance, Tails was shaped like his two tails, Knuckles was shaped like his gloves, etc. This was when I was like, 13, mind you. Anyway, I sent it off. A couple months later I recieved a response; but this response was different. It came in a normal letter, but it was thick. Rather than a single page response, there was obviously more to this letter. I ripped it open and what I found amazed me.
Sega had sent me legal papers to sign off the idea to them.
I was 13 years old, again. I kind of panicked. My Mom was wondering if I would get paid for my idea, or if they just wanted me to sign the idea over to them for free. I guess I kind of choked. I never responded; I never signed the papers. Another one of the many things I regret not doing nowadays. I probably still have their response, somewhere, burried underneath a mountain of papers and bills somewhere in a drawer in my Mom's room, where she keeps all that junk.
"That's Doctor Eggman. I didn't spend 7 years in evil medical school just to be called Mister, thank you very much"
Also: "Sonic Radion Control Racer"?
The manufacturer's description is awesomely bad, too:
Speed into action with the fastest hedgehog on the planet! Take control of the worlds fastest hedgehog and speed into action to fight the menace of Dr. Eggman. Ready to roll kids&let's go.
