If the original trilogy was remastered how would you approach the romances?

In all respects other than official being in the Alliance they are treated by the game as being under Shepard's command.  The reason the regs exist is to prevent abuse of a position of authority and they apply to Shepard in ME1 AND ME3.  He/she is not to date someone under his/her command.  Eliminating them and inserting new romance options on the Citadel would solve issues:

1) Male Shepard misspeaks when Ashley brings up Liara in that he replies:  "You think I'm interested in her because she's the only one I'm allowed to date." (when Tali and Liara have the same status aboard the ship).

2) It would solve/eliminate the Major vs. LT vs. Spectre promotions of Kaidan and Ashley.

3) It would encourage more off-ship character development and lessen the feeling of Shepard just making all the rounds between missions.  It would make the game feel somewhat more "fresh."

As a last comment - what is being proposed here is not a mere remaster, but a remake or reboot.  A remaster would not change anything except update the graphics and sound.

Not really so.  An employee can also tell an employer to eff off and quit if they feel pressured, but I know of a couple of companies that do have regulations about dating co-workers that would cost the superior their job if they started dating a person under their supervision.  Also, it's not like they can just "jump off the ship into space" at any time.  They need the ship to be in a port where they can disembark. 

I get that people here don't like my idea.  I'd like to ask them what they have against having relationships be developed off the ship and in the various ports.  To me, that would make those areas far more interesting.  As it is, after the first little jaunt to the Citadel in ME1, it's little more than a shopping center for the remainder of the game with only a few little dialogues to wrap up that can't be done on the first visit (2 with Conrad, one with Mahailovich, and one with Al-Jilani - everything else can be done in the first visit).  I liked the idea of the Kerri romance in ME:A and wished only that it had been more developed than it was.  It deserved it's own romance scene.  In the OT, I would have liked an opportunity to explore a deeper relationship with Aria or Al-Jilani or even Conrad Verner.  How about getting to know a volus or an Elcor on a more personal level?  I see nothing wrong with switching the focus of where the romances take place.  The on ship romance idea developed through talking between missions has been done in four games now.

At any rate, I'm done playing defense.  It's my opinion and only that.  Like it or hate it, I care not.

In the OT, the only place I found having your LI on a mission with you mattered was at the end of ME3 in two places on Chronos and, of course, the goodbye scene.  I found it far more interesting when you encountered Jack or Miranda during a mission, but they weren't on the mission with you.  That Miranda could literally die in Shepard's arms made it a much better romance story for me than all the sex scenes on the ship just before the final mission... and the meetup in the apartment with Miranda also felt like more a part of the story.  In ME:A, I will admit that Peebee's nomad banter about being in a romance with Ryder was fun, but otherwise there is nothing in their behavior on missions that really changes whether you're in a romance or not.

As for Kerri, I agree that the cheating aspect of it was very poorly done.  I didn't like that it occurred even if Ryder had subsequently committed to a shipmate romance.  Still, it was nice getting to know someone on the hub in a little more personal way than just shopping or doing a side quest or two for them.

As I said, part of the reason I'm suggesting it is that the ship-board romance formula has been with ME from the start.  As I also said, if we're talking remaster, I would not change a thing about the games themselves... just update the graphics and sound.  If we're talking remake or reboot, then I think it should be very, very different from the original.
