Dyansty Warriors 4: Hyper - Fall of Wu (Shu) | Wei Yan/Guan Yu/Zhang Fei

Playing Nanman first and getting Meng Huo to submit causes Guan Yu to use Nanman Armor Troops to counter Pang De's archer ambush at Fan Castle and causes Meng Huo to show up to help after the fire attack at Yi Ling. If you take 30 minutes into the Nanman Campaign, then your musou officer ally will retreat and Zhuge Liang will say they should have taken care of Fan Castle first. But man you got to really draw out the stage to hear that.

Clearing Fan Castle...uh...seems to impact nothing. If you clear it before Nanman Campaign, then your ally reinforcements show up 3 minutes sooner and your musou officer WON'T retreat 30 minutes in. This changes basically nothing.

Wei Yan was under leveled, but since I needed to make sure Nanman Campaign lasted 30 minutes, it worked out. I still ended up having to waste time at the end, and hey, at least he's leveled now.
