I'm a sucker for well done romances, in a well done story driven RPG they only add to the immersion. Doing it the right way is the key though and making them believable and not cheesy or tacked on. Skyrim's marriage was probably the worst case scenario, and Bioware's romances become more and more dull and an endless copy&paste of the same old formula, not even mentioning the "everyone's bi because players need love slaves". I liked DA:O, but probably mainly because I immediately fell in love with characters like Leliana anyway. DA2 again was Bioware's worst case scenario, better leave them out before becoming so dull.
