... What does that have to do with anything? We've had that for years.
Well, this is purely anecdote and observation on my part, but Nintendo to me is known for several things:
1) blank slate characters: other than spin offs, nearly all of their major mascots/characters are blank slates. Granted some of them have more personality than others and execute what little they do have well (that's why I love Luigi over Mario any day <3).
2) Only one character is ever playable or even worthy of note in the main game (I'm looking at you Mario).
3) A lot of their games feel kinda samey to me. They aren't bad, I do love some of them, but it does get annoying having what is in essence the same plot over and over again.
4) I don't want them to bend over to the idiotic sects of this fanbase like SEGA has a tendency to do on many occasions.
Maybe I'm just partially sleep deprived, and maybe just overly cynical about it, but I don't want Sonic to become like Mario in the above mentioned aspects. If Nintendo can prove me wrong, then I'll take this back, but until then... eh.
