The XBLIG Companion scrapes the RSS feeds of XboxIndies.com and gathers the XML and CSV data for every applicable game, updating the app's listings as the games are updated themselves. XBLIG Companion will offer easy browsing of Xbox Indie Games' selection and will allow users to purchase games for their consoles directly from their phones.
Created by Casey Young and organized by Dave Voyles, XBLIG Companion is currently in beta testing -- anyone with a Windows Phone 7 can check out the prototype now by contacting Dave [at] ArmlessOctopus [dot] com, and leaving feedback right here. Now that wasn't so difficult, was it, Microsoft?
