As much as I hate it I tend to agree with the people who claim that many Nintendo fans don't buy 3rd party games for the simple reason that they only buy Nintendo games.
Perfect example: Deus Ex: Human Revolution - Director's Cut
There was no reason to dismiss the enhanced Wii U port which is considered as best version of this great game by some people, e.g. http://tinyurl.com/nkljngg
And don't tell me it was a late port and that everyone had already played it before on other systems. They haven't.
Edit: This post only applies to Wii U, not 3DS
