I have never really had a problem with Gamestop and I think some of the complaints are ridiculous, however in regards to returning a new game, no you should not be able to return a new opened game, how easy is it to copy these things? Most of the time I have seen a retailer accept a return but exchange for the same item, and then open the game you get to ensure it is not sealed.
As for the price you get for used games? That is a choice, primarily, you can get a better price is you sell it on eBay, maybe even on craigslist, but that requires effort from you, or you can dump it off with them, requires no effort from you. You not only get less, but you have to do less, you don't pay an eBay listing fee or a portion of the sale price to eBay either, as you also don't pay a cent on craigslist. However with eBay you run the risk of not getting paid, on craigslist you run the risk of being raped and murdered, possibly eaten by some psychopath. Who knows?
Gamestop is a fine store, and as any business exists to make a profit, that doesn't mean everything they do is perfect, but its not terribly different than many other stores out there.
