Eh, you got mods, but I'm a firm supporter of controllers. Just something weird about having one hand spread out while the other clutches a small oval/weird shape mouse. But hey, to each his own.
On the lines of this, it makes me wonder if they are going to have extensive support for a controller in the PC game. I know quite a few PC games nowadays come with almost mandatory support for some kind of gamepad, usually the 360 controller (especially if the game is also on the 360). I know that the Oblivion had some Gamepad support. (Can't remember if it was actually good or not, didn't use it.)
I can agree with your need for a controller. I've found that I enjoyed playing my PC games a lot more with a controller, but only when the controls aren't complicated. Seeing as this is going to be on the consoles as well, their control scheme shouldn't be complicated, so that's not really a worry. But that makes me wonder if they are going to do the same thing as in Oblivion where the game was made more for consoles than PC, as the UI was totally borked in our version of the game. Couldn't play it without some kind of UI mod.
But yah, I'll be playing on the PC for this one. This way, if there's something I don't like about the game, odds are, someone will fix it, or I will be able to fix it myself. Mods can do wonders.
