I don't think any game franchise should die, bad game franchises should get better.
I don't subscribe to this rational, especially not for series that have 7+ games in them. Perhaps it's just me being a hipster who wants to see more brand new IPs rise up rather than just more sequels, but I feel that a series can only go so long before it just becomes redundant; you very rarely see movies last more than four sequels, and they've usually already completely collapsed on themselves by the third film.
Horrible, horrible idea. There were 7+ games before in the Mario franchise before Super Mario Bros. The recentness that the characters in a video game were introduced has absolutely no bearing on the quality of games or the abstract newness of the gameplay itself. Nintendo has kept Mario fresh with interesting new gameplay mechanics for over 30 years, why should they trash the Mario franchise? To replace it with a "new IP" that plays the same as the new Mario would have?
And even without new gameplay mechanics, a sequel can still surpass it's predecesor working entirely within the mechanics of it with quality, challenging levels.
I don't understand your comparison to film well enough to argue against it, because I know nothing about the medium of film. Maybe if films were exactly like video games I could just apply what I know about video games to them without it being horribly invalid, but they're not. Oh well.
Any games based on sports. Please, if you're going to play sports, play a real one outside.

That's not what they said at
the dawn of the video game industry.
