i would like more in better quality. romance has always been a guilty pleasure really, but the characters have to be done right. mass effect for example, just never worked well in believability. shepard was a static brick in personality and the fact that any man/woman would see the appeal in romancing him/her just killed the immersion.
i can't remember enough games where romance was the prime motivator for the story. but i would like to see it become a thing.
