Is the PC version really that much greater? My PC can easily handle it, but I like playing Bethesda games with a controller more. What system should I get it for?

PC.

There are two programs that will allow you to play it with a PS3 controller on PC. First, MotionJoy will make it so that your PS3 controller works on PC. Second is Xpadder which easily makes it so that ANY game without gamepad support will work with a controller. You can make your PC believe that the buttons on the controller are whatever key from the keyboard that you assign to that button, and you can set the mouse movements to your analog sticks.

Also, go to tesnexus.com and you will see how big the modding community is. Through mods, Bethesda games always become much, much better than they are originally and their lifespan and replayability extends by hundreds, if not thousands of hours.

If your computer can handle it get it on PC, Gaming on a PC is always better for RPGs

Well I would get it on ps3 because your more comfortable with playing it on the ps3. Its hardly a biggy if the graphics are slighly better on pc.

pc (if you have a good pc) ...not because of the controls... or the graphics.. but for the modding Oblivion mods changed the game in so many diff ways, same with fallout 3. trust me pc all the way Only problem is (like rage) you will no doubt have some bugs but it will be WAY worth it trust me
