Won't effect me. I have never bought a used game in this respect.
The only used games I have ever bought is N64 and older back to NES, and that is because I can't buy physical copies new anymore, but even then I always end up paying a little extra because I want a copy that actually looks like it is new/been taken care of.
Other than that, I buy all games new at full price(usually pre-ordered special edition as with the last few 360 titles I bought), or a year later still new but when the price has dropped ten to twenty dollars.
I know GameStop gets most of their profit from used games, which makes me laugh because they must hate me, because if I ever go there to get a game, I walk by the used game rack "bleh" and get a new copy from the new rack, even if there is a copy for half that on the used rack.
I buy new in that respect, because I know I will get everything the game originally came with. I want a game that has a box that it belongs to, not one that the cover has been has been lost and has a GameStop logo on the box with the game name. I want it to have all the original inserts(not that there are many if any anymore). On the box thing, I've just never got that. How do you lose the box, or lose the cover insert? Do people actually take out the cover insert and throw it around or away? Maybe I'll just chalk that up to stupid little kids destroying the stuff they get for no reason.
What would I call myself? A dedicated gamer. When I buy a game, it is mine(until I die). I've never sold a game, ever. The only games that have left my possession are ones that were stolen in house break-ins(back in the day they stole my SNES and all the games). Over the years though, slowly but surely, I'm getting those stolen games back through E-Bay.
