I would be for 1 option each for each orientation if there's like only 1 male and 1 female option, they could even make that character really integrated into the plot. If they have 2 options for each gender, they should really make them bisexual. I'm sure a big part of the audience, gay or straight, would wish that they could romance the one that they don't have, assuming that it's one gay and one straight each. Realistically, if they decide to to set sexuality with it, it would just be a straight and a bi option like DAO. It's not a coincidence that gay options are always the lowest number, but it's understandable since gay audience is not as high as the straight audience. 6 options are the minimum number if they're really wanted to do set sexuality correctly since everyone would have at least 2 options to choose from. 6 are the originally number, the extra 2 options were created during the extra time, so maybe they have more word budget and romance budget during that time.
I bring this up because after seeing how stretched the word budget was for DA:I with so many companions and so many romance options I have come the preference of, that i would rather have fewer companions with deeper stories than lots of companions with very shallow stories. Yet fewer companions has obvious issues.
One of the issues is that romances, specifically LGBT romances have to serve two functions. One they have to be representation and provide the ability for people to romance the gender they want. This creates a dynamic that can cause problems within the LGBT community. First if you use any kind of representation formula you need a lot of characters that are romanceable because lets face it the world is diverse in who likes inny bits and who likes dangly bits. The more characters you add or the more romances you add the more development cost. And companies always try to reduce costs, Bioware tried to do the no set sexuality in DA2 and that created a huge backlash as people claimed it implied that was making a statement that sexuality isn't fixed. Or people got mad because it made every companion bisexual. So while it gave people the ability to snog the gender they wanted it upset people who wanted games to be more representative of the world.
Perhaps the problem was trying to use romance options to do both duties. What if you had people that are part of the LGBT community but they are not romance options like your second in command, the engineer, or whomever. They just members of the crew who happen to be non straight and you only know about their sexuality because of conversations about loved ones. When someone talks about their wife or husband by using these gender specific titles you have just identified their sexuality without saying...
"Hey Protagonist just wanted to let you know I'm [blank]."
"Err.. thanks... I guess? I didn't ask and don't really care so why did you need to just out of the blue tell me your sexuality?"
If games just had LGBT characters to do the representation heavy lifting and then had 4 romance options all "bi" two women and two men to give players choice on what gender they snog. Would that be a workable model? It would allow the protagonist to be whatever they wanted in terms of sexuality and because non romanceable characters would have set sexualities of Lesbian, Gay, Bi and/or Trans we would see the game's space populated by divergent peoples without having to create so many romance options.
Just a thought. i mean it is really easy for me to say this ideas works as a straight man because lets face it in terms of representation and romance options I am not under represented so maybe i just miss something obvious because of my frame of reference. So from the LGBT perspective, not that you are the lone spokesperson for the LGBT community, does this work? Is it a viable solution to lower costs while still giving everyone the option to snog who they want yet also providing a more realistic representation of the variety of sexualities that people have?
