Ok well in the region code you can apparently add:
CPLimit = 720 ; Each territory can have a custom CP limit (default is 1000)
That would only effect WOTR (at least i suppose )
There is another line, in gamedata.ini which might be the other one:
GoodCommandPointsMP2 = 100 1000 ; 2 players
EvilCommandPointsMP2 = 100 1000
How many points would that be for the powers? I assume that the palantir power things would be a cap to the points, not the exact choice of powers..
The number 3 is waaay to hard for me to do a simple search, so i advise looking through the wotr files and the gamedata.ini, I'm a nice lad and all, but I will not spend my time searching through all those files and possibly end up finding nothing
