Decided to go ahead and do this. Figured I'd share this playthrough I'm doing just for fun with you guys. Below are the details of what to expect out of this video series:
-Minimal Grinding: What this means is that I'll still grind, but only for a few necessary characters, such as the Heroes and only a couple of the Healers/Mages I'll be using for their highest level spells. They're about the only one's I'll go for a level 20 promotion with as well. I might have to bend the rules about grinding when Book 4 hits (I'll have a separate file(s) for this just in case), however, we'll see when that rolls around. I've done this type of challenge before (minus book 4), just non-recorded.
-Super Hard all the way through.
Hope you enjoy.
