I'm a Sony fan and I haven't been drulling over this.
Nintendo's characters are more, better known, older and have appeared in many more games over time. There aren't many characters from Sony that carry over from gen to gen or that are known by the general public.
Also, Nintendo fans care about Nintendo characters much more than Sony fans about Sony characters, PlayStation consoles are about variety from 3rd party studios and don't have mascots. I doubt this game will sell 2m, let alone 5.
No troll is too much for me to handle. I rehabilitate trolls, I train people. I am the Troll Whisperer.
