Xbox suggestion future games?

Where could one go to suggest a future game for Xbox to be produced?

I was thinking that only if they would be able make a game that reflects what they are learning in school. Kinda like the Game MYST you had to figure out one clue to get to the next clue –

Or maybe even have them go on a scavenger hunt through the internet to track down clues to get to the next level (but make it reflect what they are learning in school) This would help in two ways –
1. parents wouldn’t mind so much when a kid plays for 4 hours straight
2.For Instance, my kid remembers every detail of the game that he plays – If it corresponded with what he was learning in school – I think that he would advance faster.
So do you Know where one would go to request a game like this that would actuall be reviewed by someone who actually would be interested and may have the position to utilize the info. ?
