We appear to be going round and round in circles. People are operating under the premise that this is a Japanese sales thread, so the only thing that "matters" in our discussions is the Japanese market. However, I'm advocating for the idea that the global market is incredibly important to any game developer or platform holder in general (which should be obvious), and that this cannot be ignored when discussing Japanese developers and their support.
Yes, having the support of the vast majority of Japanese publishers is important in Japan itself, but on a global scale having the backing of the heavy hitters from Square, Namco, Capcom, Sega et al is obviously a prospect that would be enticing to any platform holder, and that probably is a long-term goal of Nintendo's as well. It has nothing to do with their performance in Japan, because the Japanese market has effectively been theirs for several years now.
That's the last I'm going to say on the subject.
Having just read this and yes we are indeed going in circles. However I would still want to share some of my thoughts:
1. It's not the right idea to come to a thread focused on Japanese sales thread and advocate for global sales discussion. This is something that belongs to a Global sales thread. We can't just remove the Japanese context from the discussion here. Why not go to NPD, PAL and UK to advocate for global discussion? Why single out Japanese thread? This is most likely answered by my next point.
2) Global sales numbers are rare and far in between, you cannot meaningfully discuss global numbers and trends in the same granular way unless you have history and data like Japanese sales thread does. This threads can literally dissect how discounts affects sales trajectory In Japan on week to week basis (something that never happens unless dataholders shares such info on NPD/UK/PAL) and is able make meaningful predictions and judgement based on past trends. This is why those threads don't have the same number of discussion compared to MC threads. No other threads have this level of data. This is why the thread is annoyed at certain disruptive and bad faith posters who ignore past data to push their console agenda, usually anxious fans of other consoles worried about loss of Japanese marketshare.
3) Success is not an either/or scenario, you can be both successful at Japan and RotW. You can also be successful in RotW but not Japan. Japanese sales thread are focused on how a game did in Japan, just like UK is focused on UK and NPD is focused on US. This is a function of such threads, not a bug, not sure why the need to fix what isn't broken. Global sales are not the main focus of discussion, even if they sometimes show up to give context to discussion (but more often used to detail discussion by assuming numbers we do not have).
4) Most Japanese developers, especially Bandai Namco AND Sega, the focus of most discussions, are simply NOT pushing the hardware enough to justify their exclusion of Nintendo platforms and thus atrophying their Japanese growth potential. Nobody on MC has been discussing about high-end Capcom SE or From games missing Switch, as most regulars already understand that that isn't these companies' business model.
