I LOVE THIS IDEA.
I’m going to open with that because honestly, the people freaking out in a bad way over this are really getting to me.
Player sexual characters are cool, they’re pretty convenient- you can go after whoever you like no matter who you are.
THAT SAID, if there are enough characters to allow for it, I definitely prefer them to have their own distinct sexualities.
Now don’t give me that “DON’T TALK ABOUT REALISM IN A GAME WITH DRAGONS” bullshit. Characters are written as people- they’re fleshed out, much like your OCs probably are. Think of your OCs- they have their own abilities, flaws and preferences that all are a part of them. They also probably have a sexuality.
Yes it’s an RPG, but the characters that aren’t your protag are allowed to be their own people. Based on who you are, they will react to you differently. If you’re a man and they’re a gay man, they might take interest in you. If you’re a woman and they’re a gay man, they can’t develop sexual feelings for you because of THEIR sexual preference.
People then worrying about the “depiction of gay/bi/lesbian” characters are also freaking out way too much. Every person is entitled to a sexual preferences but who they are is more than their sexuality. If a character has a flaw- they have a flaw. They aren’t representing all gay people everywhere as flawed just because they happen to also be gay.
If it’s in terms of content, Traynor and Cortez, the gay romance LIs in ME3- their content was probably only less than the other squadmates because they were new characters in a trilogy that had the same protagonist and recurring squad mates all the way through.
So yeah, am I excited about more complex social dynamics? You bet your ass I am~
