I have just noticed that all of my new units are veterans. I think I own the Sun Tzu (Army of Africa) wonder and you have the Great Wall (Cinturon de Hierro). For some reason the wonders descriptions are mixed up (the pictures are correct though). I will put that on my list of fixes. I wonder if Sun Tzu will be too big an advantage for the Nationalists. I guess a lot of units are event created, but I can still build quite a number of veterans and that might prove to be an unfair advantage. Perhaps I could include an event that will make the wonder obsolete (IE if the Republicans capture a certain city). I will also put that on my TO DO list to think about.
Playing the turn now.
