The Grand Prix is perfect as monthly online content, but we fans also want CNK's adventure mode inside CTR:NF.
Hear our prayers, Activision and Beenox.
In CTR: NF has the CNK race tracks, but why not his adventure mode?
Make a DLC at a fair price and include it in the Nitrous Oxide Edition for those who already have it.
This offline content would increase the game's lifespan, and it would definitely increase its sales and more people online. Listen to the fans, Beenox and Activision.
But don't leave the Grand Prix aside.
