Agreed. It's one of the reasons why I play the games besides the good looking men.Relationships between the characters is one of the most, if not the most important aspect of the game to me. You can have a potentially good storyline but the game could still be poor if there's no relationships (either romantic or non-romantic) which was obvious in Final Fantasy XII where the relationships were dire. However, relationships can make up for where the storyline lacks. Certainly in terms of Final Fantasy the character relationships are extremely important as even Kitase/Toriyama have said Final Fantasy titles are almost 100% story driven.
For me, I believe relationships between the hero and heroine or other characters are very important. Love is another side of a life. And we're supposed to see these characters go through so much and then find love.
I can't explain it very well, but what I'm saying is the love side of a characters story is half of who they are and we HAVE to see that side of the character. It completes them.
Kind like the line, a man's not a man till he's loved someone...or somethin' like that.
So, yes love stories in FF series are very important to me.
