Allow me to present a rather frustrationg algorithm for you.
In order to get the desired result (which is "A Playable Role Playing Game System That Anyone Can Enjoy") Please complete the following equation.
Time / Character creation, Combat mechanics, Modifiers, skills, attributes, merits, quirks, backgrounds, starting races and bonuses, penalties, lore, bestiary, all other world-crafting anomalies.
(Convert minutes to an appropriate numerical value to encompass the creation of all the above things.)
Everything is easy. EXCEPT Combat. Combat is more like this:
Combat = melee - defense + bonuses provided by any number of the above anomalies.
Which in theory seems easy. To me, this simple equation looks like
A = (xy/3) [(Grr + %50 chance of blah) + (nonsensical skills - Opponents nonsensical skills)]
ALL divided by the fact that I hate math and why can't I just make a game that people can play without being giant picky troll-faces who hate everything!?!?!
