This is not so. The entertainemt industry and electronic industry is at their highest sales right now. Movies, games, accesories etc. are all having a greater income than before, and is continue to grow.
One of the main reasons behind this is the so called "streamlining" of not only games, but other things too.
We can quibble about the facts- for instance, I'm pretty sure electronic entertainment is up but other forms of entertainment (dining out, cinema, etc.) is down- but the point is entertainment is down. I think something like a TES game is probably great value for money for most people- lots and lots of stuff to do for lots and lots of hours- so it's a good buy.
The point is, there's a depression, and the people who own Bethesda probably own other companies that aren't making as much buck. They have to make up the deficit somewhere. Into the gap steps the gaming company they own. And in order to make sure the game is as successful as possible, it's made to be derivative.
(Also, what is with Todd's 'like iStuff' comment? Apple will be just another company in ten years, if it isn't already. [It is.] I hope he realises this and adjusts his aspirations accordingly.)
