ALL businesses strive to maximise financial return - you can't reasonably begrudge Bethesda for behaving like any company would do in their position. The problem with commercial success it it tends to stunt creative growth, and Bethesda are not immune to such a phenomenon. The bigger the market, the more "mass appeal" the product must have.
So be upset that the intellectual depth of this series has waned, but rationally concede its inevitability. Decrying it (though sometimes a satisfying outlet) is ultimately pointless. The tragic reality is that intelligent, maths-and-literature classic RPG players like you and I are a curious relic that barely registers on the market demographic.
It took Morrowind two years to reach 1.4 million sales. Skyrim achieved nearly three times that amount - in two DAYS. The intellectual devolution (and consequent growth of mass appeal) is not going away, friend.
And always remember - we have at least mods to shape the game into something superior. Naturally that isn't ideal - but having the power to correct the game is nonetheless appreciated.
So onwards and downwards, I say!
