Is there a game where you can play as a wild horse

Yes. You can play as a wild horse at secondlife (dot com) Its is a virtual game where you must download and then buy the horse you would like, however it can be anywhere from 13 to 20 dollars. You join a group and register as a wild horse. There are Indian RP games or, old western games, even stables if you so wish to be ridden or adopted too. You can RP with several different colors of horse with the same body as well( Color packs are extra). It will be confusing at first but it is plenty worth it. I suggest getting a Mesh horse if u do join :P
