Just came from playing an extremely satisfying and actually quite challenging HoI3 game as Republican Spain. Yes, I played and won the Civil War for the eleventh time. But you never know which garrisons, etc. will fall into National hands, so its always exciting.
This time, it was actually a challenge since I had less men for most of the war, but when my armoured divisions finally were produced, I broke through their weak spots and smashed their lines. I was winning by then, but the enemy had managed to break the initial stalemate in Andalusia and controlled almost all of it, all of Extremadura and a lot of Castilla-La Mancha, along with most land west of Burgos (which I captured relatively early on).
Started in March 1936, didn't saw it end, but by late January 1937 the nationalists were hopeless and I was achieving victory after victory in crushing their advance towards Valencia as well as their lines of defence along the Guadiana.
