Is it my imagination, or is ability score generation method 2 massively overpowered? Method 3 gives you seven points to distribute amongst eight ability scores. Method 2 gives you a bare minimum of 8 points and a maximum of 32 points.
It is slightly unbalanced but not terribly so. I'm gonna be amending this method for the final version of the game. However the chance of having eight abilty scores with a score of 4 in each is 1 in 65,536 so I'm not too worried
