Make a horse game idea? (Based off of Sprite)?

Ok i had this wonderful game i just made up!
it is a 3D horse game in 3rd person, and you can be a wild horse in a never ending world (Like minecraft my worlds never end!). You can make a herd find Indians that greet you and if you want you can be there friend or they can own you but you can leave any time, and there's a bad guys hunters and army men. You can eat drink and fight for your life. And there can be a multiplayer selection and you can have a mate.

It sounds nice to me and very beautiful!

If you are going to do this please say yes and start maybe a fourm or a site that i can join and help.

If you not going to do this please just don't say anything!

No thanks… O.e
