Rumour Buster: The Nintendo 64 Classic Mini Game List 'Leak' is a Batch of Old PDF Files

I personally don't think a rumored N64 Classic is true, but that link doesn't debunk anything. It is just saying that those manuals posted are old manuals. Of course they are old manuals, nobody is expecting them to be updated to reference a N64 Classic (or else it wouldn't even be a rumor, it would be as good as an announcement).
The question is: why these games? There are other popular games not included, and there are marginally popular games included, and there's even one included that's not released in US. The list is not a random one though, it looks like something someone gave a lot of thoughts into deciding what manuals to release. That's the root of the rumor, and that "why these games" question is still unanswered convincingly with facts. Again, I don't think it's true, I think the list is just coincidental, but there is just no evidence presented to disprove it.
