Couldn't it be argued that they created new characters out of necessity, since the SNES there really hasn't been many classic characters created. There have been plenty of new franchises, but recognizable characters? Not so much. I mean look at Smash Bros., besides the Pikmin theme, virtually all the franchise characters are from the NES/SNES/GB days and older.
Not necessarily. Couldn't the original Star Fox have just been Spaceship Mario? I feel like that's the difference between pre-N64 Nintendo and post-N64 Nintendo. Today's Nintendo is far more apprehensive about releasing a game based on a great new idea without slapping an existing IP on top of it (i.e. Epic Yarn). If Star Fox had come out today, there's a chance it would have been a Mario game. It might be a safer bet in the market but it constricts creativity. There's significantly more artistic freedom in creating something brand new.
Star Fox with ground missions? Why? Just make a Star Fox game. I'm not saying it can't work but there's no need to reinvent the wheel. Let Star Fox be Star Fox. I feel like the series' main issues arose when developers strayed from what the first 2 games were all about. Focus on what made the series so great in the first place. It's a mostly on rails shooter. Stop trying to make it into something it's not. Like I said, don't make half a Star Fox game and shoehorn ideas that don't really work. Those ideas for ground missions could easily evolve into an entire game built around those concepts.
Don't get me wrong. I'm not railing against sequels and demanding new IPs. Rather, I'm advocating the idea that Nintendo stay true to a series. Every franchise must evolve or else risk becoming stale but sometimes the ideas don't make sense. That doesn't mean they toss those ideas out. Instead, save them for when it does.
Looks like I need to post the list, AGAIN.
No, you really don't. I'm aware that Nintendo has created new IPs so your list is unnecessary.
Don't stop making Mario and Star Fox but not every great idea had to be retro-fitted to be part of those franchises.
This is what I'm specifically taking about. Forcing ideas that don't really make sense or changing an entire game to be part of an established series (i.e. Dinosaur Planet into Star Fox) damages the brand and the game.
