Hey. I wrote a little document on Map Making. It doesn't cover .WACs or the fundamentals of the MED. What it does cover is the topic of enhancing your maps to make them interesting.
I intend to expand it further to cover areas like using events to spice up a map. but for now it's just item and enviroment tips.
I hope you like it.
