I work in the video game industry, in the IT department (thus no real game creation skills, but I do support the artists) and came up with what I thought was a stellar game concept. I spent a huge amount of time writing out the gameplay mechanics, describing the art style, outlining things that will make this game valuable in the eyes of executives, estimating production costs, etc. I have a speech/pitch ready and everything. I found the right people to talk to but never made enough of a connection to actually pitch the idea. It was disappointing but in the end I think I understand that people with money to spend on a game concept don't have the time to hear out people who day dream and not take action to achieve their ambition. It's like saying you want to be an astronaut as a kid but never doing what it would take to achieve that - it's not like a lottery where some random guy is picked. In time I hope to have a better chance at pitching my own idea, but I expect that's still years away.
