I follow this thread with some sort of morbid curiosity, but this made me think...
Quoted from stangbat:
Think if John spent time actually getting shit done instead of dreaming up things that will never see the light of day. But getting shit done is hard. Sitting on your ass dreaming all day is much easier.
Honestly, if John could have had a secondary person whose job it was to run the business side of things and keep his dreaming in line, I wonder how things would have worked out. From my limited interactions with John from the MGC, and as I've stated before, I don't believe that he was trying to be a criminal mastermind or steal everyone's money - he really believed his ideas that he had could be created and would be better than anything that came along before. And perhaps he was right, but we'll never know because his business acumen was so bad (or non-existent) that he was never going to get anywhere.
Walt Disney was a huge dreamer too and went bankrupt multiple times. It wasn't until his brother Roy came in and ran the business side and corralled his brother's ambition into a way facing forward that Walt's dreams started to be a success.
From having seen John's ideas for things, he was a wealth of pinball ideas, but he kept coming up with small ones that ultimately didn't mesh. If he had someone nearby who when he would stop working on Magic Girl to figure out the new lighting system for KISS (which was cool) who could have said, "Knock that off or do it when you're not here, we need to finish this!" and who could have coordinated the building of the machines, I actually do think that it would have worked and could have been great.
But... we'll never know, sadly. Dreamers don't make good businessmen.
