Yeah, if you email Nintendo all you will get is an automatic generic "thank you for your concerns" response. They will not make a game centered around a random town in an old region when fans are calling for Hoenn remakes instead. I am not saying your idea is bad it certainly doesn't warrant Nintendo spending millions and millions of dollars on a game that won't have much success. You should definately make a ROM hack possibly of HG/SS where the graphics are better and Lavender town is already set up and you will have a ton of people here who LOVE hacks including myself who will play this game and get an idea of your adventure you are creating. Good luck with your idea though!
