Call me when somebody finds an 'idea' guy has skills outside his ideas and has produced a completed game that has gone to market. The "idea" of the "idea guy" is nothing more than children trying to justify their lack of real work on real products. Learn to code, to create artwork, and see a game through to the end. Only THEN are you allowed to tell anyone else what value ideas have.
If you've never made a game, either individually or as part of a team, then you're not an idea guy. You're audience.
