The only Burnout game which can not be played on the Xbox 360 (except for the handheld games) is Burnout 2: Point of Impact.
This NEEDS to be rectified! So the campaign to get Burnout 2: Point of Impact on the Backwards Compatibility list starts here!
After a little bit of searching I found out what to do to get a game added to the Backwards Compatible list.
We all need to send an email to backcomp@microsoft.com and request that Burnout 2: Point of Impact is added to the list.
