It would be fun to adjust the costs of many items, not so much for the sake of balance as to make it a new optimization problem. I've been thinking along the lines of ricks03's suggestion. Everyone must have 100 points leftover, with bonuses and penalties that change that. e.g. IFE costs 30 extra, MA/UR/BET give you back ~50, etc. Double the advantage points spent/gained from mines. etc
