Ah, an out-of-context snippet in the OP. My favorite. I honestly don't know much about Rimworld, but did he promise realistic relationships? Was the relationship system a key facet of the game? There is lot of outrage in this thread towards a person seemingly based on a single post. That's always a good sign to step back and take a deep breath.
And before I get some misguided post from someone who is ready to step in and do battle with the evil of the world, I can understand disappointment and wanting to change a game because of its views and understanding of diversity. I have trouble understanding knee-jerk outrage to anything that seems to stray from the majority GAF views.
Edit: Especially on a game still in early-access.
Bi-erasure is a serious issue that has caused genuine harm to millions of people for a long time.
Enshrining that erasure in the relationship code of your early access game is one thing, a forgiveable thing, but doubling down with some bullshit "research" and "personal experience" when called out on it takes us into darker territory.
And yes, the relationship system is a core part of the game, managing your colonist's moods is a key part of ensuring your long term survival and relationships play a big part of this.
Like the game. Like the dev. Can't fault him for basing his npc behaviour off personal experience, especially since he seems open to discussion and change.
You "can't fault him" for his game denying the existence of Bi men, and then trying to justify that? No fault there from your perspective?
