Games designed for PC are much harder than games designed for consoles. This is because it takes a certain base level of intelligence to operate and maintain a PC. While I'm sure there are nuclear physicists and great philosophers who own an Xbox, the fact is that all it takes to possess one is pocket change and chimp-level intelligence sufficient to plug in a power cord and press the 'on' button. Ask yourself why there are almost no turn-based or real-time strategy games for console -- and the few that exist, like Civilization, are dumbed down and simplified. It takes no more computing power to make a complex strategy game than a simple one. It's because the people using consoles don't have that minimum-intelligence cut-off that PC users do. In order to turn the maximum level of profit, developers making games for consoles have to ensure they can be used by young children, computer-illiterate seniors, the mentally deficient, Apple users, and Republicans.
The result of this has been devastating for PC users. We used to get games like Morrowind; now we get Skyrim -- pretty to look at, but deliberately dumbed-down to be friendly and easy to use for the 9 year olds ("console kiddies") who bankroll Bethesda with their mommies' video game money.
If you go back and play games which were designed for the PC first and later ported to consoles, rather than the other way around, you'll find that they are almost inevitably more complex, require higher critical thinking skills, and have more immersive gameplay designed to last many hours rather than the ten minutes between the end of The X Factor and when the Hot Pockets come out of the microwave.
