I don't see how that's a double-standard. We're talking about the respective chances of both systems, by looking at their library (past, present and future), right?
So, a game that opens at 90k on the Vita is absolutely a good success on the platform. It's up there in the highest first weeks. Of course in the grand scheme of things it's niche, but that's exactly my point, the Vita is a niche platform with niche games that sell to a niche that largely already owns it.
In the Wii U's library, 90k is definitely not going to be up there in the highest first weeks. The whole discussion started with michaelius stating that the reason why the Vita had a better chance than the Wii U in Japan was because, using this week's charts as evidence, "software sells on Vita and doesn't sell on Wii U."
My answer to that is that the software that sells well on the Wii U will sell in the hundreds of thousands to millions and will sell a lot of systems. The bigger titles in the Vita's library aren't selling too many systems. Whether Phantasy Star Nova is bigger than Sen no Kiseki is irrelevant -- Mario is also bigger than Donkey Kong but you're not gonna see a 6k week when Donkey Kong releases.
