No, but if you're only thinking of the mods then that's just stupid.
PC: Better graphics for computers that are better than the Xbox (so pretty much every dual core PC)
PC: Mouse and keyboard is superior in every objective way, and if you still prefer controller you can plug one in.
PC: Steam big picture, sit in your couch and play a 1080p game on a giant ass screen.
PC: Mods, like you mentioned.
PC: Earlier patches
PC: Cheaper than xbox games.
PC: Steam overlay, chat with friends or google things ingame.
And btw, why are you paying 60 usd for it? Have you looked at the prices at all? It's understandable if you live in Australia or something, where prices are high. But just take a look at the steam price, it's lower than 60 usd. Take a look at amazon.com, lower than 60. I bet you could use a site like pricerunner and find it for lower than 30 usd. This myth that games cost 60 bucks is getting tiresome. I buy new games at 33% less all the time. You just have to google the game and find the cheapest store.
