The problem with buying used games is that they can be utterly fucked and all warranties are void on used secondhand products and I highly doubt that whomever sells you a broken (or damaged) game is going to pay you back. There's also the matter of stores such as Gamestop screwing you over, they sold me a used copy of Valkyria Chronicles for 470NOK when the retail for a brand new one was 300NOK... I bought it used because it was virtually impossible to find anywhere in this town. And the disc is damaged somehow and the game freezes, I contacted Sega about it but they said it was out of their hands since I bought it used and Gamestop would have to fix it. They didn't, because I hadn't paid extra for a warranty slip, which costs around 6$ or so. I don't buy used games (or other products) at all any more, I mostly buy them from England at Platinum prices.
Here in Norway, a new console game usually costs around 600NOK while a new PC game is between 350 and 400NOK or possibly less. Prices aside; the PC remains the best platform for the more advanced gamer with all sorts of customization, mods, hardware possibilities and of course the fact that the games themselves are often a lot more deep and complex (and infinitely better in many respects). Try playing Civilization IV on the PC and then strain through a session of Civ on PS3 or 360. PC versions of console games are even better sometimes, such as Mass Effect 2 of Fable.
Don't get me wrong, I like to play on consoles but I simply love playing on the PC (Off to play Mount & Blade again! 
).
