I prefer that SE just left Marriage out of the game entirely. Not for the sake of equality, religion or even wasted dev resources.

Minors (teenagers) play this game and although online romances occur all the time, I don't like the game actually encouraging these relationships..whether they are straight, gay, lesbian or even worse...Adult & Minor.

Yes it is a parents responsibility to monitor their child's online activities but anyone who is a parent knows it is very difficult and any of you who become parents will find out for yourselves how troubling online relationships can be with teenage children especially.

I played FFXI with my two daughters for many years and I had to set quite a few players straight about some of the inappropriate behavior and attention given to my younger daughter especially. Again, I fully realize it was my responsibility to monitor it and ultimately my "fault" for allowing them to play in the first place, but my point is that these dangers already exist without the added pressure of "kids" wanting to "marry" someone they met in an online game.

This can and many times does lead to not just hurt feelings but can lead to Bullying and even Stalking (both cyber and real life).
I just don't want anything in this game that encourages that sort of behavior so please just leave Marriage out of it.
