On the lighting only striking once though you are certainly off base. Chuck E Cheese was big in it's own right and I'm sure you have heard of at least one of the other companies he started; it's called Pixar.
Yes, Bushnell created what probably became a part of Pixar, but calling him a founder is pushing it.
No doubt though he is a smart business man with multiple ventures under his belt. I do believe he really has a passion for what he does as well; the fact that he is still doing this in his 70s when he surely has plenty of F-You money says something about his passion for this industry.
And, no, Bushnell had nothing to do with Pixar, which had been around for 4-5 years at LucasFilm before CEC sold off Kadabrascope to Lucas in a fire sale. Pixar started with Ray and Catmull.
Bushnell has started more than twenty companies and is one of the founding fathers of the video game industry.
Okay, sure. How many are still going, and how many didn't completely sink the money of the respective investors?
I get that Bushnell is a smart game guy, but IMO Atari was a lightning strike he's been trying to replicate ever since.
