Press "A" to select the game and read a description of it. Before purchasing it, you may select "Get Trial" to briefly try the game.
Highlight "Buy" if you want to purchase the title. You are asked to confirm the purchase. If you have enough Xbox Live Points on your account, the game download begins. If you need more Xbox Live Points, they can be purchased directly from your console, or from many retailers, including grocery and video rental stores.
Back out of the Xbox Live Marketplace by hitting "B." Scroll to "My Xbox," then scroll right and select "Games Library." Scroll to the right and open "All Games." When your game download is finished, it appears here. Highlight it and press "A" to open it, then choose "Play" to start the game.
