MMGN writes: The importance of the videogame exclusive to a platform brand cannot be questioned. The exclusive defines and establishes a brand in a market, allowing consumers to associate the product to the platform it's exclusively available on.
Nintendo thrives on its first-party exclusive titles. You think of Nintendo, you think of Mario. Sony's advantage in this case is that there is no distinctive brand or character that is automatically associated with any PlayStation platform, and that gives the company plenty of freedom to be creative and risky.
