Nifty. I like that taints give a bonus as well as a penaly. It made me think of the system in Vampire and other World of Darkness-games, where each character defines an archetype as their Nature. If you managed to "live out" the trait defined in your Nature, you gained a Willpower boost.
In tabletop rpgs, I always thought such rules were a bit construed, since we were just roleplaying away, anyway (the archetype system in Vampire was a great aid for that, though). OTOH, I think it makes more sense in computer games to give a tangible boost for acting in character. I've actually been thinking on something similar for my game LoSt, but as "codes of conduct" which give you skills/bonus/reputation if you follow them (vow of poverty, duelist honor, lawfulness, chivalry, whatever).
Anyway, keep up the good work. The project seems promising, and I must say the art looks mighty nice (though I found the Paranoid icons a bit vague, placeholder-ish).
