I like to play napoleon and give a region to prussia and have them be my ally. I need to have them stay put for a while. I always attack england first. their navy is a pain the but and their army is always the hardest to beat. Once I get england and do not take them but sell them to other country. What I like to do is to liberate scotland and then give away england to them. They love it and they will be your ally to the end and I also do the same with ireland and give wales to them. I then go back to europe and then I also have all my allies in germanic country and kingdom of italy fight russia and austria and then slowly i get austrian regions... then vienna goes out easily. russia I like to take a boat all the way to the black sea and march straight to moscow during summer times.
