You mean like how the Xbox has improved over the years?
Oh wait, it hasn't, it's the exact same hardware as in 2005.
There is your answer.
LOL right, because games like Gears of war 3 look just as good as Gears of war or Skyrim looks just like Oblivion. Right... we haven't improved at all..... It's not about the hardware improving, it's if Bethesda can truely push it to it's limits. Don't comment if you don't know what you're talking about because the graphical quality of games has improved over the years as developers learn how to push the tech that they have at hand.
