Backward Compatibility on the Xbox 360 has been a hot topic among gamers ever since the 360 was announced. Microsoft eventually promised that the new console would be able to play some Xbox games, and launched with a backward compatible list that included more than 200 titles.
The Xbox 360's ATI GPU and IBM CPU were vastly different from its predecessor's, which housed a Nvidia GPU and Intel CPU, forcing Microsoft's engineers to rely on emulators. This technological hurdle yields a list of backward compatible games that includes Barbie Horse Adventures, but doesn't include critical darlings Psychonauts and Chronicles of Riddick: Escape from Butcher Bay. In addition, some games that were once on the list have now jumped off, such as Freedom Fighters, Sid Meier's Pirates!, and Mortal Kombat: Deception.
GameSpot News talked with Albert Penello, Microsoft's director of global platform marketing for Xbox, to find out the ins and outs of backward compatibility, and why some games make the list and others don't.
