About F-Zero, I am saying that it is stupid that people caused a hissy fit over it since it WASN'T F-Zero and it WASN'T ripping it off. They used the Blue Falcon as a test and people got upset.
And no, see, that's why I said I didn't think you know how the word gimmick works in a positive way. Being useful doesn't make it not a gimmick. A gimmick is literally just a "unique or quirky feature to make it stand out". Granted, most of the time, it is used for things that do it for the sake of doing it, but by definition, it's just a unique trait. For example, nearly every Zelda has a gimmick that defines the game. Doesn't mean it's just for show. They almost always switch up how the game works in an interesting way.
As for 3rd party support, I think you miss the point of why it is important. I don't care. I know that the logical thing is to own two consoles (or a PC and Nintendo one), but most people don't want to buy 2 systems and some people don't like digital-only.
Nintendo not having 3rd party support means that people who want 3rd party games are not going to buy Nintendo consoles just for ONE company's games in addition to needing a constantly upgraded PC or a more expensive PS4 or XBO to play everything they want to play. People who want 3rd party games are more in number than those who ONLY want Nintendo games, and this should be obvious when comparing the useerbase for the systems.
Now, as gamers, which console is selling better is irrelevant to us directly, but the low Wii U sales affect Nintendo, and affecting Nintendo affects us eventually.
So sure, you not wanting/caring about 3rd parties is fine, but Nintendo not having their support will ultimately mean their console sales will continue to be garbage and this will eventually lead to them either trying to get money in more shady ways like everyone else.
It also leads to what we have right now, which is a drought of games for 3 months (in North America anyway). Nothing between Splatoon & Super Mario Maker. Meanwhile, 3rd parties would've filled that void.
