Engadget.com has a great article on the coming game titles for Windows Phone 7 and the Xbox Live integration. Check it out at https://www.engadget.com/2010/08/16/xbox-live-launch-titles-for-windows-phone-7-finally-revealed-we/. I used one of the comments from the article for the title of my post. Seemed fitting to me.
