What is the frequency of updates to the library?
When the Xbox 360 launched, Microsoft released a list of over 200 games that were backwards compatible with the Xbox 360. Every few months Microsoft would release an update to the list. Most updates added 30+ games to the list and updated a few, some of which did not run very well on the first release. After six updates (the last being 2007-11-27) and two years after the release of the Xbox 360, Microsoft all but confirmed that they would be calling an end to this ongoing project. Their reasoning was that there was not enough interest to make it worthwhile for them to continue their efforts.
