I think it's also important to point out that Zelda games since the 80s have been one of the best pieces of software humans have ever invented. So many classic titles that have enthralled generations of gamers. You wouldn't get an immersive experience if these games were buggy or didn't have compelling stories and art.
I don't think I've ever heard of someone describe a Zelda game as having a compelling story before.
They have great storyTELLING, I guess, since it's presented fairly beautifully, but "man wants to take over world, hero must stop him, princess also involved" is not... particularly revolutionary.
Successful stories are seldom revolutionary. What matters is, if it is well done. And Zelda was very well done all around. Graphic, music, sound, characters and yet unique enough, to create that franchise.
(I only played the gameboy version ages ago, but I still remember the atmosphere).
