politics is just a title given to a larger sccale, group-lead version of our opinions.
Someone may be conservative, but not agree with everything the conservative party say. Thats individualism for you.
As far as putting someones spec. on the world of today in to their work... I think FFXIII will be more about the game itself than any other issues.
I read something saying that FFXIII will be set in a similar world to that of the film Equilibrium. A controlling government/empire, fear stirrs in the heart of any who bad-mouth the governments leadership etc etc.
As mentioned previously in the post, if we dont like it we dont have to buy it. Just because we likee FF doesnt mean we must buy every game

You've got no need to be concrened, IMO.
