I don't know if you are familiar with the modern idea of achievement points so let me humor myself for a moment. Achievement points are a bragging right nothing more. Even on MS live service achievements are merely such. Just be happy with some of the achievements actually rewarding you for your grind to it. So yes they are worthless if you are not a bragger. Doubt they will ever have meaning. Sorry if this sounds harsh, but what do you expect fr a system that was designed exclusively for a bragging system?
