Anyways yea, i REALLY hope they take a long look at this thread and ponder on it.
The 3 way mix/match with tiers in all of them (weapon grades, tier system for skills, and hopefully a tier system for stats) would be nearly the perfect way to make a customizable game!
I can already see it now...
It'd be easy to follow and compare, it'd be way easy to implement. And honestly? That's possibly the most customization I've seen proposed for any game! Spore's got nothin on this system! (if it works)
