I think I can link the main character in NFS 2015 to NFS Prostreet
(Please note that this post is not a question, but a possible relation between characters from previous installments.)
(note image chosen was just for fun)
The main character (the player, so you) has a lot of shared traits with the main character in NFS Prostreet Ryan Cooper. First of all, they both don't talk. Now that you think about it, the main character in most to all of the games in the series so far have been silent. Back during Cooper's campaign in 2007 to overtake Ryo, he would never speak or take off his helmet, just like the reference to Prostreet in Undercover. The reference goes something like this: an officer claimed to have Cooper in the back of his car, not even willing to speak or take off the helmet [reference over]. This leads me to believe either the character is mute and doesn't want to reveal his identity, or that he can speak, but just won't take off the helmet. In installments after Porstreet, the main character has been silent for the most part (all player characters minus Jack, Zephyr and whatever the officer's name was in Rivals). This leads me to believe that either: Ryan had just started his road to victory and had a return in the new game, or that [for the most part] Cooper had always been the main character. Either that, or the main character is, you.
Tell me what you think, I guess? 🙂
