In all honesty, I prefer the Federation:First 150 Years/Autobiography verse as it feels more Star Trek then the novels and am happy to use this as references. For starters, it gets rid of the stupid Andorian four genders crap.
I'm fine with four gender species but not Andorians or Aenar. I always see them as two genders because that's what I saw onscreen.
The Andorian ceremony implied in "Data's Day" didn't indicate four genders to me to be honest.
I always figured group marriages and polyamory was common (nothing indicates Shran had just only one partner [mind you I consider the last episode of Enterprise is nothing more then an RPG game and anyone except Archer can die depending on the parts you take) in Andorian culture.
I can't believe how much of a dill I was back when I posted these. Definitely good I took a break and found more Star Trek EU books over the years.
My past self, you are a ding-bat for thinking Andorian four genders were crap and stupid.
