I own both versions (PC and X-Box). Yes, you can mod the PC version and yes, you can use console commands and so forth, etc. etc. etc. The games, quests, etc. (in there basic, vanilla content) are the same. I would say if you have the extra money to do it and you want to do it, then hey...it's your dime do it. Personally, for me, no I wouldn't. Why? Because I don't see the mods and console commands as reason enough to warrant the extra outlay of money. I would rather save the money and get me maybe a better Video Card, other games, etc. This is just me and my opinion. The only reason I have both is because my X-Box and the games were bought for me this past Christmas, so I had no say in it so to speak. But, then again, I'm 42 and a tightwad with $$$$$.
