Had a thought of something I'd have liked to see if ME2 romances returned to the Normandy in ME3. I'd like to have seen Shepard able to go down to their quarters and have interaction nodes with them there like we get in Shep's cabin in ME2.
For example, for jack we can go down to the sub-deck and then we can sit on her cot with her, with an arm around her as she presses her head into our shoulder. We could also click on the table opposite her and Shepard sits on that while Jack paces about, making randomised 'talking' animations as she steps back and forth (kind of like the animations they used when she sits in his lap).
For Thane, we could sit opposite him while he makes more 'talking' animations, maybe stand in front of his gun display while we both consider different weapons, maybe even meditate while holding hands.
Miranda, we could sit on her couch (Get Liara the hell out of there!), have another 'talking' animation somewhere, maybe consider reports at her desk together.
Tali, you can work on something in engineering together, lean on the railing looking up at the drive core together, work at her console together.
Garrus, he can pace about 'talking' while you lean on the rail looking over the guns, you can both work on calibrating the weapons, and you can use that console to his left to kick his butt at some kind of strategy game.
Jacob's a little harder because his room has been removed, but you could have him down opposite steve at the workbench. Then you can have Shep and Jake upgrading a gun, 'talking' again, maybe even help him with his workout or something (Spotter, I think they call it).
any other ideas?
