Why change something that ain’t broken?

To answer the question, watch this.

(note:foul language).

The point is pretty much though 1:35. Nintendo makes the game with gameplay. For the most part, the rest is fluf. There doesn't need to be much of a story to Mario or Zelda. They are games built on being fun.

Pokémon sez hi

Well Game about Evil Link? that could be so good

LINK IS EVOVLING

LINK EVOLVED INTO...
FIERCE DIETY LINK!

If characters developed...
Mario and Peach would be in a failing relationship. They'd have a son.
Link would realize talking f*cking rocks, propose to Zelda be king of Hyrule, and kick ass.
Samus gets hooked up with Master Chief. We'd have the most badass couple in history of the universe, they'd have 1 child, and that child would end up saving the Universe. Every day.

I think it would be weird for Mario or Link to talk, I'm fine if samus talked, it wont sound so weird to me.

If they evolved? Like Pokemon?

i doubt they would.......most of their games are aimed at children
(that's where most of their sales are coming from)

You'rea couple years late. Samus had extensive dialogue in Fusion. Then people whined.
