It is sad, this year we will not be seeing an Assassins Creed game on the Wii U at all. This will be the first game since the Wii U launched in 2012 not to be coming to the Wii U and as we learnt earlier this year we most likely won't be seeing Assassins Creed games on the Wii U in the future with Ubisoft slating poor sales as the reason behind the decision. In the case of the now current generation game Assassins Creed Unity there is actually another reason which is Ubisoft stating that the Wii U is not powerful enough to handle Assassins Creed Unity in comparison to the Playstation 4 and Xbox One.
Ubisoft creative director Alex Amancio explained to RedBull:
“It couldn’t, it really couldn’t. I mean this is why we from the beginning, this was going to be a new-gen-only title, because the crowds aren’t aesthetic, they actually have impact. If we did anything to hinder that or to reduce that it would have a detrimental impact, it wouldn’t be the same experience. I don’t think that would be fair to fans, to sell the same game but with different levels of experience. Even the seamless nature of the series and the scale of the game right, we couldn’t do that. We never load Paris. It wouldn’t be possible, in our minds we’d be cheating fans by providing a lesser version of the same game.”
The same argument can't be said for Assassins Creed Rogue which is being developed for consoles that are below the power of the Wii U. However Assassins Creed Rogue will obviously not come to the Wii U because Ubisoft is afraid of poor sales, or they are just afraid to have to put more effort to make a Wii U version which I found to be better in both Assassins Creed 3 and Black Flag which were better on the Wii U in my opinion.
