The Chronicles of Riddick: Escape From Butcher Bay was awesome. It was one of the best games for the original Xbox, and was one of the only movie-to-game adaptations that was good. So why isn't the original game backwards compatible with the 360? Is Microsoft too busy making more Barbie games backwards compatible?
Actually, in this case, the blame goes to Starbreeze Studios for the lack of backwards compatibility. It's not that Starbreeze didn't try and make it backwards compatible, it's just that it's not really possible. You see Starbreeze did things to the original Xbox hardware that no other company ever did. They pushed the Xbox to its limits to make Escape From Butcher Bay above and beyond any other game on the system.
