The subject title is a question of a hypothetical matter. Hear me out...
A few days back, I ran into this video that goes into the state of the Wii U's third party support situation. (Warning: the video contains strong language.) The video's point is in no way surprising to me and it's something that I think most sensible people would agree on. Nevertheless, it got me to thinking about the "hows" and "whys" when it comes to Nintendo platforms and its third party struggles. In particular, the way the Wii U's multiplats have been handled to this point challenges a commonly-used 'reason' why the Wii and Wii U had/have such shaky software support from third parties: power. Already a notion I find to be more cliche than factual, it got me to think about something else... what it the roles were reversed between Nintendo and the other hardware makers?
Based on what we've already seen with the Wii U and its PS3/Xbox 360 multiplats (and lack thereof at times), why is there such a strong belief that Nintendo's shortcoming in recent years is because its platforms haven't been powerful enough, especially when we have examples like Sniper Elite 2, Mass Effect 3, and Injustice that suggests a different issue entirely? Suppose that it was the Wii and Wii U that were clearly at the top of the ladder in terms of console horsepower... for what reason(s) would other publishers and developers take them more seriously? If it's a matter of sales and revenue, Nintendo's platforms wouldn't make anymore sense as undisputed powerhouses than they do as is. In the case of the Wii, it being a $500+ console would have been nothing but an absolute disaster for Nintendo, and third parties would have paid it no mind anyways. The answer I anticipate here probably comes down to multiplats, but when you look at the history of most multiplats on Nintendo consoles, as well as how they're being handled now on the Wii U, how exactly would a more powerful system inspire more confidence and better effort from publishers that would still likely be making games for the other systems on the market?
This is in no way me trying to defend Nintendo's decision to make the Wii and Wii U what they are as consoles. Frankly, I think the Wii's success and innovation justified how powerful it was and I believe that the Wii U would be where it is, no matter how powerful it was. This is just my curiosity coming into play and wanting to know exactly why so many people suggest that if Nintendo would simply build more powerful systems, it would gain much stronger support from publishers. When I look at not only what has happened in previous gens, but also what is happening at this very moment, there is just nothing I see to make me believe this claim. Nevertheless, I'm open for answers. :P
