One of Microsoft's biggest announcements came today at the end of their press conference. Starting August 30 of this year, gamers will be able to download full Xbox 360 retail games via an On-Demand tab on the dashboard.
30 games will be available to purchase when it launches, with new games added weekly after that. Lastly, Microsoft has said that gamers will be able to directly purchase their games with a credit card without having to add Microsoft points. It's important to note that Microsoft Points aren't going anywhere, it's just in this rare case where gamers are paying big bucks where it is overlooked.
