You're trying to fight actual facts with anecdotal evidence. Why? The console sold a metric shit ton of games, despite what you and your friends saw.
To focus on both, you're going to have to quantify how developers like epd Tokyo and the Mario kart team etc etc to produce some expensive M rated aaa murder simulators with a ton of expensive marketing To attract that audience to the console. People who are suggesting that they just stick some ps4-like parts in the console and magic happens and all is well with the core market and all (or even most) western third party support returns really do need to face reality.
The actual software they sold outside of Key Legacy Franchises, and their Wii branded games were shovel ware.
Games like MArio Kart sold so well because it was bundled, and marketed well along side the Wii. Same goes for Super mario Galaxy press blew that game up and made it a top seller for the console and one of the top selling Mario games.
There are only a handful of IP's made by Nintendo that actually sold really well. And most of them outside of Wii Sports and Wii Sports resort were first party legacy games. The rest were crappy third party ports, and shovel ware.
That's what I think he's getting at, Nintendo Didn't capitalize on new costumers, in getting them to buy into Nintendo made games again, or create new games similar to splatoon that could have curated their own unique library that continued to reach different regions outside of japan.
And because of that you have people in this thread talking about their quality/diversity of their output, which isn't great.
To your second point I agree you can't just put part's in a box that come off a check-list and think the console will draw third party developers in. But you can reach out to them and maybe have them develop exclusive games for you instead of wasting time on a port that more than likely won't move units.
Nintendo has to prove them selves viable again to companies. If they go the trajectory they've been on, it will end badly for them. They need change, and that change comes from better PR advertising agency the one they have is god awful. Sony replaced their with one that's associated with google.
I say it was a really smart move and has payed off for their brand. Nintendo needs to do the same, and needs to have a keynote with western developers. The fact most of their games are still coming from Japan is not a good sign for whatever NX is.
If they go the route of having a cheap console, I feel it will spell doom for them, since they will in some way rely on gimmicks to sell it.
If they have a moderate console with decent specs, and have been in discussions with western developers, they might have a chance in making a library that will speak to different regions.
But they need to have other part's of the company to make decisions and not have it all on JAPAN.
