If it were me, I’d do something like not really focus on what their actual “real” sexuality is unless it is somehow relevant to the plot. Then if it is so something like make them a 1 or a 5 on the Kinsey scale instead of a 0 or a 6.
I don’t think games should be required to do, I’m not trying to force some sort of universal bi/pan agenda. I’m just saying it personally annoys me when I am locked out of pursuing a character just because of the gender I happen to be playing as because I typically don’t play games multiple times. It also annoys me when games don’t allow you to pursue all characters. Like in BG3, as far as I know, all characters are bi/pan but not all are poly. The game forced me to pick between Astarion and Karlach, for example. I put 100 hours or so into the game before I quit. I’m not willing to put over 100 more hours into it just to see what would’ve been different. It’s just a waste of my time.
An alternative approach is only having “sex scene” type content gated behind gender, but everything else can still be seen by friends. E.g., anything a character would eventually tell a lover they still tell close friends. Which is still sort of annoying but not really as bad because you can easily just look up a sex scene, but experiencing things like dialogue and special quests in game isn’t comparable to looking it up on YouTube.
Central Hyrule on horseback in BotW was such an amazing feeling. TotK didn’t ever catch that level of action, but everything else was more fun. Plus it has a lot of QoL changes that helped. Opening chests with full inventory comes to mind. I was upset BG3 beat it for game of the year but the competition was really tough.
It’s been nice if they had a “perpetual fallback license” approach where you are granted everything you’ve subscribed to for at least 12 months even if you cancel subscription.
