Hence the phrase, "...as easy or complex as you like and still be a pretty good read..."

Even if you don't go full complex or know much about medieval combat, a gamed fantasy encounter still puts together a pretty good story even in layman's terms.

Hacking a computer in game and knowing little to nothing about computers and/or networking? What kind of description can you write for that after the game?

That's a pretty bad call on their part not to, at least, give you a little prep for what they would expect. Especially since you were the GM first.

What did you do? Did they try and modify the dice roll depending on your knowledge of medieval combat?
