Hi all,
In the past few days I have been wondering how games set the difficulty of a player attacking something. In other words: I want to hit the goblin, what determines how difficult my attack is? So far I found the following possible ways one could determine the difficulty of an attack (all types may or may not include modifications to the roll, I am just trying to highlight the basic mechanic):
Fixed difficulty like in Dungeon World. No matter what, your target is always t a 7 or more.
Defender ability like in D&D. Your target is the defender's Armor Class.
Attacker ability like in the Tri-Stat System. Your target is your own ability.
