With the PC Version, it's nice that you can mod your games with custom items, weapons, ect. I remember the Grim Reaper equipment someone made when I had it for PC....
But now I got it for 360. Go Figure. Regardless, Elders Scrolls IV is an amazing game and I've already Preordered Skyrim.
P.S - ANY Xbox 360 Wired Controller (Madcats or Official that uses USB) works for ANY game that is Games for Windows OR is marked on the back. Oblivion, however, you may have to hot-key the buttons/sticks on your controller (I cannot remember exactlly)
EDIT: When it first played it, I skipped school for a whole week. God save us from Bethesda!
