Mmmm... is there lower IQ among console players...? Seriously, they are just as people who play on PCs, darn it! And what problem would a console offer at playing a western RPG, explain me!
The problem with consoles is the interface: the controller. You see, there's a reason why spreadsheets are used so often to process and present information: that's what they are designed for and are very effective at doing just that. But to effectively navigate a spreadsheet, one needs a certain interface: a keyboard and mouse. Since consoles don't have that option (well, the Dreamcast did, but a legion of Sony Mind-Zombies unfairly killed it), the need to disseminate information in a different way, because the interface is so cumbersome. That's why Todd keeps running around and telling everyone "no more spreadsheets!" But I bet that Zenimax uses spreadsheets everyday to work out Todd's paycheck, among other things. Heck
he probably uses them everyday, too! Truth is, important information is almost always presented in spreadsheet format. And at this point, there aren't many of us that aren't familiar with the format. So it works. But if you're primarily playing on a console, presenting the information in spreadsheet format makes it difficult for you to navigate, bogging down the game, and ultimately causing people to complain about said interface. I spent a great deal of time in the Morrowind forums, and I don't recall anyone complaining about the interface there. It worked. And although Morrowind made it to Xbox, most of the players in that forum primarily play on PCs. That game was designed for PCs. The Xbox conversion was an afterthought--Bethesda didn't really know if it would catch on and make money. Oblivion was designed from the ground up with the console player as a primary group. They didn't do too well with the menus, because it was some sort of amalgam of a PC and a console interface. Just like Mr. Miyagi said: "Walk on road, hm? Walk left side, safe. Walk right side, safe. Walk middle, sooner or later, get squish just like graqe." I argue for the PC side, because my experience is that it is a superior way of playing games. Some would rather play on a console. Fine. I've played many games on many consoles over the years (from the 2600 on), and I just prefer PC gaming. I think many people who play on consoles would agree, if they had a PC that could play games, and would give it a shot. I'm hoping with this new 10-year cycle for consoles will drive developers, and gamers in turn, to the PC as the primary development platform (like DICE is doing with Battlefield 3).
But it has nothing to do with "IQ." It's all about the interface.
