I'd heard that Cullen's romance didn't end due to the lack of marriage.
My wedding wasn't boring to me, but my husband and I planned all of it. The clothes, the location (Renaissance Faire,) the person that officiated the wedding, our vows, getting mead instead of the champaign offered in the wedding package. Even down to our single tiered Lego-topped wedding cake.
A video game wedding would put my character into a position to where BioWare decides all of the ceremony. What my PC wears, what s/he says and how the ceremony works. Sure, I'd probably have a few options to vary the dialogue, but I don't see myself having fun. I don't find that engaging at all. I don't think there is anything wrong with it, it just isn't for me. This is all a matter of a opinion. I'm not going to say you're wrong for your PoV nor am I automatically right.
While my real life wedding wasn't boring to me (especially since the best man locked his knees and passed out in the middle of the ceremony), I don't find it engaging for a video game.
<edited for tone. That sentence came off as pretty rude and I think I had misunderstood your point.>
If something like this made it into the game (say, a DLC that focuses on action with an optional wedding for the PC and LI,) I'd like to keep to optional at the least. That's all. It isn't anything personal (hugs to Hana,) but an onscreen ceremony something that wouldn't agree with me. If nothing else, I'd find that a little immersion breaking. Not everyone that considers themselves married has gone through a public ceremony.
I know someone that's been with the same woman for 17 years. They have a little girl, and they share an insurance policy, file taxes and do all the things that a husband and wife do together. Yet, they didn't feel the need for a wedding or the name change. I know that's one anecdotal example, but I've seen that couples living together like that isn't as uncommon as a lot of public perception might suggest.
I do agree that showing the ups and downs of a marriage is a cool idea. I would have enjoyed that with Garrus, as an example. If done well, it could be nice to see. Shoot I thought a romanced Garrus and a FemShep already acted like they were married, and in a good way. I'm happy to see that kind of relationship expanded upon.
I don't agree about the wedding though nor making any sort of onscreen ceremony at all. However, I enjoy some of your ideas BBM. I think we can agree to disagree here.
