I love all your GxG romances, as a lesbian I was desperate for any stories that contained stories about us that treated us like heroes. Even your non romanced characters are great. Sauzer was very 3D and he was my favorite in Loren surprisingly due to his different motivations. A lust for gold and redemption is a powerful story and the first time I could truly believe in the Holy character. In fact, first time I could understand a Greedy character and empathize with them as well. Not the sad tale, but the firm belief money could make it better.
So more pulls I guess? I love characters who have somewhat subtle pushes in different directions. One reason Karen seemed a better romance than Chambara was there were different elements at war within her. Something that seemingly contradicts but not actually opposites? Brutes that are vicious and insanely violent with a mind like a razor are my favorite villains, its like they could have been a genius but brutality was their vice and determined their fate.
Or an intellectual character who finds that all of it was a waste (for some reason to do with backstory), they are intelligent but instead of being arrogant, find all of their time studying and learning a loss, still intelligent, but resentful of that time that could have been used on more "practical" routes.
The caring sweet character that tries their best to be kind, has someone or something (not an item, but an idea like a home) incredibly dear to them that make them blind to reason when it is put in danger, and prone to fits of anger and violence when that happens, especially if normally they are a peaceful person and it isn't played for laughs.
Things like that.
NPCs that are already together are also amazing. Ramas and Dora together was pretty cool, but Dora and Ramas as an already married couple would have been interesting. 2 traveling heroes who are very much together and past the honeymoon phase, who are one oiled machine (like Loren and the PC 20 years later).
As far as Romances:
I have seen a lot of different things where the man is very feminine and could pass for a woman, but very few where a woman is very masculine and could pass for a man. I have always been attracted to Butch women but rarely see them much. If you ever watched Sailor Moon, Sailor Uranus was a well done example and one I have not seen sense. If not, a woman who is more handsome than pretty and hopefully a warm personality. Tough, but not necessarily boisterous, I guess is one way to put it.
Also, I would think it would be great where there are only 2 romances but they are more in depth and can respond to the situation more. Imagine the content of 6 romances being put into 2. Not necessarily less romance content but pack into 2 characters that can develop with the story and decisions.
