So, why does it feel incomplete and pointless here in Skyrim?. I mean, you marry someone and he/she might have a shop that gives you a couple gold coins every now and then. They can act as followers. But, what else?. Personally, I would've introduced marriage to TES as something that goes along with the main-story of the hero and not just some side-quest. In an open-ended game with such a rich story like TES or the Fallout series, I would like the Marriage system to be implemented with a little more care, so that it feels like it should be there in the first place.
I would like to see more of this in the future. Just not as a side-quest.
That is all.
PA: Am I being nit-picky about this?. I know it was the first time Bethesda toyed with this feature..Do you guys agree on any of this?.

I do like the concept, though.
