So I was trying to come up with a table free version of the old TSR Marvel Superheroes RPG, the one which used the color coded universal table.
I didn't come up with one but while I was playing around with ideas I did come up with a strange mechanic, I'd like to hear some feedback on.
The basic idea is 1d100+stat vs vs difficulty number (50 is standard) and one must meet or exceed it. On its face it seems simple. However stats can be -30 to +30 with 0 as average and in increments of 10, and this only determines success or failure.
The ones die determines success magnitude/grades of success. So if you roll 72 vs 50 you succeed and get 2 grades of success. If you get 79 that's 9 grades. Skill push grades of success up. So
if someone has a stat of 20 and a skill of 5, they only have to roll a 30 for an average test, and get at least 5 grades on every successful roll.
