So I was thinking the first after reading about the new Dirt4 game would be good and the second idea I just think would be cool!..
Wreckfest Academy - A mode where you can learn skills, techniques and practice to become the best banger racer!
Rival System - A game system that keeps track of your rivals... Where you can score bonus points by hitting or taking down other players that have either hit or wrecked you and would work for both online and offline play. I think this would make for an excellent career mode feature as well as keeping track on friends list to highlight who to aim for!!!
