If one thing lacks the Zelda series IMO its the love part of the game
perhaps they just didnt bother because of it being a kids game? who knows. Besides its an over 11+ age rating
Anyway I was disappointed right back at the end of OoT where there was a chance for something more with Zelda.
On that note same goes for Saria, or Malon
You see all this fan artwork with Link and Midna together etc and it makes you think maybe Nintendo should have considered making it more
serious with the whole relationship thing, perhaps a bit of jealousy etc
IMO I also think it would be a good way of getting to Link, someone kidnapping or even killing the girl he loves.
It would make the game a lot more emotional and I do think you would get even more attached to it with a more intense emotion like this.
