I would be vary of making the faction point system so... extensive. I mean, this is supposed to be game of blocks. A physical game, if you will. All of this seems an awful lot like building an entirely new game, with it's own rules and point systems, on top of the existing sandbox, and letting the sandbox serve as a simulator for individual actions and encounters. This might work, in a way, but I'd much rather see this "faction point" business be kept to a minimum and balance the game with block-based features.
