I made an AAR and included saved game files in how I usually set up Germany in HOI3 TFH. It has proven successful for me over and over and hopefully it will be of some use to you. Check it out, peer around through the saved game files and perhaps you can learn something that you can apply with your own style to make your games more fun and interesting. The link is below and in my signature. Hope it helps! Have fun all...
