Yea epic is the most balanced speed.
The difficulty between prince and king seems a bit steep. On prince i can dominate with any game styles. On king the only way to win the game seems to be radical expansion and conquest of the weaklings. It's a game style that i don't like. I prefer a small kingdom with high culture and science.
One thing i don't like about Civ 5 are the city states. It's way too expensive to deal with them. I prefer to start the game with more civilizations instead. Two days ago i played a game with 22 civilizations on a tiny duell map ![]()
