Why people nitpick about the gender of the leader? Political correctness or not, it's a fact that history favored men, thus it's natural that they had more accomplishments. On the other hand, it's not right to downplay women saying that they were chosen by Firaxis only because they were women.
I'd rather see a constructive criticism about how to play Poland. What are their strengths and weaknesses? How to best play them? How their bonuses mix and favor them? How to counter them?
Really, how come we're discussing gender instead of strategy about a, well, dunno, a strategy game?
