The last 10 turns I played in chapter 2 is about homosexual issues and am bullshit tired of this poorly veiled awareness crap!
I don't think the chapter matters. I've been sitting on the first map maxing out research and collecting cards while keeping the enemy capital surrounded. The issues keep advancing even if the story hasn't.
In general the game doesn't approach the issue with any subtlety. The views of the characters on this are easily refuted, yet the dialog options are limited to either submitting to the whims of your subordinate or professing some unreasonable bias.
As someone that was intrigued by the debates I find the representation in the game to be a mockery of the arguments on either side of the discussion.
Definitely an example of what not to do when injecting a serious issue into a game.
