I am slightly torn on this one
On one hand I was complaining how Russia once again gets Catherine and is still permanently stuck between Peter and Catherine, within the confines of the 18th century, instead of getting like... anybody else at this point (especially of the middle ages).
On the other hand, I have always liked Catherine the Great - and those are mighty words coming from a Polish country which was annexed primarily because of her actions

- and for some reason she was my favourite AI leader of civ5 to deal with, so it is nice to see her back, especially as she looks great and has great bonuses... Sigh, okay Firaxis, you win with this particular "cliche" leader, fine, once again I am going to embrace Catherine.
Random fun and somewhat heartwarming historical fact: when Catherine was 14 year old girl she (along with her horrible narcisstic mother) visited the court of Frederic the Great. Frederic immediately felt a) contempt towards her mother and b) respect for her gentle, intelligent and well educated daughter, certainly seeing there his own relationship with his abusive father. Hence he sent her mother to some tertiary table during the feast, whereas he sat teenage Catherine on the most honorable seat next to himself, and spent the feast talking with her about philosophy, art and science. That's also when he got the idea to recommend her for the marriage with the certain equally young crown prince of Russia...
It would be great if some leaders who met each other, or at least lived in the similar times, or had similar themes, had some unique lines for each other. So when Catherine meets Frederick they respect each other both in war and in friendship and refer to the older days...
