Yes, I agree - so the question remains:

Why is this a feature that the game designers think in need of changing "because the Americans could not cope with it"? (which is roughly translating the interview quote)

Obviously the European Gaming Community did not vociferously demand a change in concept, but the American Gaming Community did?

I have me doubts there...
