mechmouse: When I walk into a shop, and I get a new dialogue option due to a incidental datashard or read email, then Hell yes.
I think putting romance options in, with out it effecting other romance stories was a bit of an oversight.
More so when they designed same sex relationships, not to have the option "Sorry you're looking at a Stereo Output/Dual Input situation"
XYCat: So the problem is that although you can reject the second romanceable character, the rejection dialogue option is not worded the way you wanted?
Its a matter of immersion
The team put huge efforts into creating emotional responses; writers, voice actors and animators all doing their best to make you believe that bunch of pixels on the screen are real, or at least real enough to make you feel something.
Romancing is such a significant part of the game it covers at least 3 (that I know of) long branching quest lines.
The also decided to make one of those exclusively lesbian, yet in the dialogues with River when talking of past partners I could only reply as exclusively heterosexual.
As scripting and writing go, these were easily avoidable. There very next thing that should have happened after deciding to make Judy a purely lesbian romance option should have been to ensure that same character choice mirrored in other connected quest lines.
Even excluding sexuality, having completed one romance quest line the option of "I'm in a relationship" should be unlocked in any other romantic quest.
