This is not what I said at all.
What I am saying is that sometimes denying yourself a console even if you are a fan of certain series that exclusively comes to it MIGHT not be a rational choice, no matter how it is rationalized inside your head. I think I wrote it out pretty lengthily.
To put it in the context of the RPG's: It is as if you say hm, okay that Xenoblade 2 comes to Wii U, but you cant afford to buy a Wii U cause you already bought a PS4/Xbox One. For what will those consoles offer in terms of your preferences?
I understand that it is usually that people are fan of multiple things, and that those things compete for your time and money, but I do not think it is irrational to buy a Wii U "just for one game". If it were a 499 console, or even more expensive, yes, that position would be more rational to me. At this price point, however, and the barren landscape of the hack'n'slash genre, I just do not see the alternative.
Again: if you are a "fan" of hack'n'slash genre and Bayonetta, but playing COD:AW and AC:Unity on your new PS4/Xbox One is a bigger priority for you now, then yeah, I would reconsider if you could describe yourself *mainly* as a Bayonetta-fan
