Xbox 360 enlightenment is a state of mind, youll know it when the sensation comes.
This can only be achieved when your house only has a Xbox 360 and not a Wii or PS3. You must also by your definition have a gold suscription and own Halo 3.
You dont have to destroy your PS3......just dont let it stay inside the same house as your 360. You can......but u wont get enlightenment.
