I disagree with that. The writers don't have to do anything, besides following some basic rules of storytelling. Too many options are what make "romances"{Statement: Oh, How I hate the use of that word}, minigames.
Agreed. It doesn't have to get to absurd Bioware levels. I hope if Obsids does include romance, that it isn't presented as "who will you choose?", but that each companion has a well developed arc whether or not they're romanced. Instead of romance being a feature, I would hope it's natural part of the character development, and that the decision to become romantically attached or not would be analogous to other big decisions you would make for non-romanceable characters. Basically, instead of 'achieving the romance' or not, it should be a choice that has interesting consequences either way.
