Breden definitely thinks so.
I tend to like romance in CoG games when it brings opportunities for other things I like:
- Getting to know interesting NPCs
- Character-driven rather than plot-driven momentum in the story
- Drama!
Of course you don’t need romance to have those things, and not all romances make the most of the opportunity. Some of my favorite CoGs have no romance; others of them wouldn’t be weakened if they’d left it out.
