Bethesda VP of marketing Pete Hines has said the number of different user hardware configurations and the ever-present threat of piracy make PC much more of a technical challenge to develop for than consoles.
"From a technical standpoint, yes, the PC is a headache," he told Joystiq. "It just is. A million different possibilities of hardware, drivers, etc.
"As you saw with Rage, all it takes is some bad video card drivers and years of hard work comes off as 'buggy' when in fact it's a really solid, stable game."
id Software's John Carmack went as far as to call Rage's troubled PC launch a "cluster f***".
On the subject of piracy, Hines said: "Unless you decide not to make your games available for PC, it's a problem and you have to deal with it.
"So we do the best we can to protect it without resorting to Draconian measures, and we continue to enthusiastically support our PC fans with things like the Creation Kit and the ability to create and add unlimited amounts of mods and content to your existing PC game.
"... We try to do some things with the UI for PC folks to have the best experience possible," Hines added, noting that PC gamers will be "very pleased" with the performance of Skyrim.
