I think romance should be important part of the game but it should not take over the plot.. There should be more than a few romance options and each of them should be distinctively different. (personality, behavior, motives and quest lines etc) Mass Effect games had terrible romance subplots (flirt-flirt-flirt-exchange words-you are about the finish the game-than boom, sex-now you are dating... wait what?) Since when people wait for critical moments and suicide missions to have sex? All jokes aside, game doesn't even have to include sex (i mean original cyberpunk does and it would be nice but it doesn't really matter) Whats important is both companion relationships and romance options should be effected by your actions. relationships, romantic or not, should be meaningful. You should be able to change their minds when it comes down to it. You should ultimately be able to effect their personalities and their state of mind. (both dragon age and fallout new vegas did this really well) There should be companion quests where you can make your companion trust you. (and your actions should worth something)
