Don't think I've ever heard of someone buying a video game just so they can see it sitting on a shelf.
Considering how many of my 500+ Steam games are never going to be downloaded much less played...
I'm sitting here trying to figure out what I was thinking when I wrote that, seeing as there are a few movies I have on my shelves for no real reason other than saying I own a copy. I also admit to being pretty old-fashioned in many regards - such as the fact that (apart from the majority of my college textbooks) I tend to hang onto anything I've purchased forever.
The issue I have with giving consumers store credit tied to a publisher is that sometimes people trade in games because they don't like what they've played or the business practices of a particular publisher. It makes it harder for these people to "vote with their wallets" by forcing them to purchase a game from a company they may no longer want to support.
New look, yay! It's cute, too! I love the cute look of Extra Credits! I also like the new and improved podium!
So used games;I tend to buy my games new, whenever I can, but I'm a bit more open to used games if I'm short on cash and find a game I want that isn't available new.
Really, saying if people buy used, they're a bad person, is ridiculous. Pirating games, that's another thing, but I have every right to buy a game that's been used. I mean, yeah, I feel sorry for the publisher and developer, but I have my own funds to worry about, and I find a better option in a used game, then, well, I'll take it. It's also hard to feel sorry for publishers when they use such tactics to weasel their way into our wallets and suck out as much money as they think they can get away with.
Also, Jim Sterling has addressed this issue a LOT. In fact, when Dan brought up Steam, I felt the need to post this video... even though it's not about used games:
