Main point is about immersion and realism.
No idea how you got: " Appearance of gay characters" from what I wrote. I clearly stated it is the amount, and how they are so over-eager to share that they are gay. Gay relationships in this game vastly outnumber heterosexual realtionships, which makes no sense if you want people to actually.. exist..
And yes, playersexuality, breaks immersion. I feel like this is another one of those situations where they removed all consequence from the game. It is impossible to fail a romance quest line in this game..(which brings us back to immersion)
Outside of the main companions, can you tell me which characters directly inform the player that they are gay? Off the top of my head, I can only think of the deep gnomes in the Grymforge, Aylin and Isobel, and Barcus and Wulbren. There are others who are alluded to being gay, but they are not "over-eager to share that they are gay". Would you mind giving me some examples outside of the three I have mentioned?
