I've been thinking of something of a skill system for Mutant Future. Not just a "spend a few points and add a bonus to your rolls" system, more like actually improving your own abilities and even adding on more. This would start modestly, such as being able to throw up to a light load with little or no penalty, tossing a sword at an enemy 50' with a reasonable chance hitting them or swiming for a quarter mile at without rest. Higher ranks would allow for feats of skill such us hurling your full carrying capacity one-handed, throwing your sword a whole mile away and cleaving out a seven mile long trench from solid rock or swiming for days on end in either chain mail or plate armor, possibly even towing dozens such suits of armor with him.
Now all skills would be divided by ability score. Thus you would have Strength, Intelligence and Willpower based skills. You'd also get a number of skill points per ability bonus for every level to be spent on that abilities skills. So if you have a third level pure strain human with an Intelligence score of 18 he'd have nine points to spend on Intelligence based skills, mostly allowing him great benefits from his intellect instead of adding to or subtracting from any Intelligence based rolls. This would include more and better information abuot occult lore or ancient technology on a good roll. If you don't have an abilit bonus in one score, or worse yet have a penalty, you don't gain any skills or skill points related to that ability.
So my question is this, is this a good idea or is it crazy for an old-school style game?
