u'd be surprised. i think a lot of people play wow.
It's ultimately up to philly. but i think this is a great idea.
you can sell any item or wow like companions, mounts, armour, questables, wepons, enchantments. also you could offer services like tailing or mining or something where u can fill out a order and someone with maxed of that skill can get what u want and then u pay them via wow or PP or mp or something and then u get the items
this could be liek a business here like xbox.
