They\'ve done a similar (or maybe the same) thing in Sims 2 - I haven\'t played it yet so I don\'t know how that works - so surely a similar system tied to skill stats isn\'t too difficult. Just working out how a stat decreases is the difficult part (and, I guess, what appearance should be bound to which stat, etc.).
But I like the idea that once you\'re good at something, if you stop practising you\'ll slowly become worse at it. So even if you become a great mage, if you then stop doing magic for a month, when you come back to trying magic, you won\'t be nearly so powerful as you were before. That\'s a brilliant idea, whoever came up with that one, because, by the time PS is in its final form, some of the characters would have had time to perfect almost all the skills (unless they get wiped :S) which would have the \"what now\" feel, and take away from the realism.
