not every choice grants you points, and there is a fricken war going on. you don't stay neutral during a war. And all the choices are compelling, if you do not pick a side you are really just hurting yourself by restraining your natural character.
I think I need to point out the difference between making a neutral decision in one scenario, and making a light and dark decision in two separate scenarios (leading to a neutral reading on the alignment scale).
Were talking about the second instance. If I choose to play a character who thirsts for revenge, but saves every innocent life he comes I'll end up making both light and dark decisions... and I'll be punished for it.
