Not really sure how to answer that I pretty much only buy new unless they no longer make a game and it's ridiculously expensive for a new copy then I'll buy a used one begrudgingly. And I very rarely buy digital unless it's a really good deal or if it's steam.
If I know I am going to want to play for a looong time I buy retail at launch. If I am unsure I try to get a fresh copy from Gamefly and if I dig it I get to keep a brand new copy for usually around 45 bucks.
Corner camping isn't playing, its the video game equivalent of tripping people as they walk by
I went with "I buy majority of my games retail new, but will pick up a preowned copies if they're cheap enough and don't buy digital" as that was the closest to my purchasing habits. I don't buy digital games if physical copies are available and for certain developers I refuse to purchase their products new so I buy them used to ensure they don't get any of my money like Bethesda.
