Apart from sticking with the original game play from the original series which i am glad your doing. I would like to suggest that you consider including some little things in Cossacks 3 which does not alter the game play in anyway such as: Flag bearers for the nations. Just to give that sense of realism and pride of playing each unique nation. Additional flags flying on important buildings like the town hall or barracks for example. National fife/marching theme to your respected nation perhaps adding a flutist that does this so you have a choice of drummer or flutist. Enhanced/realistic sound effects like the ones used in Empire Total War - DarthMod for example. 3 or 2 ages that you can research at the town hall 16th, 17th and 18th centuries. Cannons with soldiers rather then cannons being moved by ghosts. Maybe having a playable pirate faction/nation with there own campaign to. Well that's all i can think off just a few little things which hopefully can still be implemented into cossacks 3 without the original game play being effected. P.S: Would love to see a roman, medieval or modern version of cossacks made in it's game style.
