Back on Track - more ideas

So I'm back on track writing power descriptions after a short hiatus. We are now almost done with most of the C's. 34 of over 200 powers done...ugh.

As for the weakness conumdrum I think I'm going to have it be a mix of the below ideas on a previous post.

Characters start with 5 ranks in powers for free, they can take upto to 10 more (total 15 ranks) if they take an equal number of weakness ranks. In addition if a power goes above a certain rating, I'm thinking 5 right now, then they will begin to develop more weaknesses. The total number of powers may also affect this.

Another idea a friend of mine had was a karma/motivation scale. Works something like this.

Your character has 2 motivational ideals - say glory and money. For every major action that bring glory or money to him he gains some karma points. For everything that he does that makes him look dumb or costs him lots of money he gains negative karma. (Notice both are gains). the GM tracks how much karma the character has and the player can opt to add X amount of karma to a roll on a 1 for 1 basis, but he doesn't know if he has any positive karma. If he spends more karma boosting his rolls he also gains negative karma. The GM can use the negative karma to boost the rolls against that character. This would allow a character (if played intelligently) to have some really truly awesome moments, and for one played badly to be smacked like a bitch .
