Yeah there's plenty of healthy polyamorous relationships out there. It's important we remember to be respectful of that. When it comes to the game, I'm not too sure...
It's from my understanding that polyamory is about romantic relationships, rather than casual sex/open relationships being about sex only? So in a way, from what we've seen, neither SH or Halsin would be considered polyamorous at all.
In the Halsin forum, one of the complaints was how Halsin seemed to be disgusted with the word "relationship" which disappointed those who obviously want a relationship with him. So it all just screams casual to me. I'm no expert though.
