It's been a pretty darn interesting year for the Xbox Live Indie Games service. Back in July Xbox Live Community Games took its new 'Indie Games' title, and a whole new pricing and rating system was banged into place. Since then, a number of indie developers working on XBLIG titles have reported seeing rises in sales and the whole service has definitely picked up a bit more steam.
Of course, with the new rating system in place - in which Xbox gamers can rate any game out of 5 stars - it means you now have a pretty picture of which games are actually higher quality right now (as opposed to the Top 20 most-downloaded, which often has much stranger stuff in it.).
