Let’s imagine that your character is involved in a sword fight with an opponent.
How would you prefer the game to resolve this?
Option 1) By setting a fixed difficulty for the fight:
So, the writer might decide that you need a Melee stat of 50 to win the fight.
If your Melee is 50 or higher then you’ll always win, if it’s 49 or lower then you’ll always lose.
Option 2) By randomly generating the outcome:
So, the game might generate a random number between 1 and 100.
If the number generated is equal to or lower than your character’s Melee stat then you’ll win the fight. If it’s higher than your stat then you’ll lose.
What do you think?
(The random number wouldn’t need to be 1-100 for every conflict, any more than the fixed number would always be 50, the writer could experiment with different ranges and probabilities depending on how difficult they wanted it to be.)
