Unfortunately there is sometimes this big disconnect with the outside world with game development. There are a lot of people who want to be the ‘idea guy/gal’ I know quite a few of them who think they could make a living just being an idea generator. As such there is no job to be just the idea person. You have to work just as much as anyone else on the team to bring an idea to fruition and to receive any of the profits, if there are any. Anyone can come up with ideas, not everyone can make those ideas reality.
As CrimsonWingzz said, it’s not a new idea. There are already quite a few well developed games that do this, and many many games that tried to do it but failed. For every successful project, there are tens, if not hundreds, of failures.
If you want to see a game like this be created with your vision, start learning some game development, from either art, programming, design, take your pick or try and learn them all. Being ‘lazy’ gets you no where and no team will want to bring on, and especially share any percentage of the profits, for a team member who doesn’t contribute to the work for being ‘lazy’ and ‘greedy’. You don’t want to be the only one in the row boat not rowing, that person usually gets left behind, or worse, thrown overboard.
franktech has it pinned with the quote “1% inspiration vs 99% perspiration”.
Learn how to do something on the game (art, design, development), work many many hours to build a prototype or conceptualize your idea and prove your concept, then pitch the game to others with the work you have done, show that not only can you come up with an idea but your following through in making it happen by working on it. Then you might be able to assemble a team of like-minded individuals to work on the game.
