"We did it with Games On Demand and the response has been really good. I think people like to see the dollar amount. We never intended to ever mislead people," Greenberg told , talking about the Games on Demand service using real money.
"I think we want to be transparent about it, and so it is something that we're looking at. How can we be more transparent and let people see it in actual dollars? The fact is that you've got to think that we have one service that we're offering around the world."
For a long time Microsoft has been criticised for the Microsoft Points system instead of adopting proper money prices on their virtual store items, like Sony does with the PlayStation Store.

"So there's some challenges to that, but we absolutely did it with the Games On Demand, response has been good and absolutely it's something we're looking at doing."
What do you prefer? The Microsoft Points system with 'top-up' cards available in retail stores, or being able to see exactly how much you're forking over? Hmm.
