Ok, so I was thinking, if 343i has gotten their stuff together, and after fixing whatever problems people had with Halo 4, and with some free time, perhaps they could add a vehicle customization system similar to the one in Forza 4? I would LOVE to make some unique skins for Warthogs and Ghosts! In addition, after players submit their creations, 343i picks their top 10, and the community votes on their favorite. The top pick is then applied to whatever vehicle it was designed for in matchmaking. Also, there would be different vehicle categories, so you could have both hot rod flames 'Hogs and bacon-skinned Ghosts! In addition, any skins you make, download, etc. could be applied to vehicles in custom games.
So, what do you guys think? Would this be a cool feature?
