Can we have a collaboration between GTA and NFS?

well you sort of already can. Just replace all GTA V cars with real ones. GTAinside has some great models to download and with some Shader tweeks Im sure you can make Los Santos look similar too NFS. Only catch is you can't play Online because you will get banned for moded files. I'm tempted to do this myself and replay the entire story with real cars.  You can even tune certain downloaded cars with custom parts!
