Not sure where you are based, but in the US, I'm not aware of any retail shops that sell used PC software or games. Are you buying used PC games from people on ebay? Don't think I'd feel comfortable paying for something and then hoping that the original owner won't try to use it at the same time

I'm in the US and a vast majority of my PC games are used. I had to buy them that way because there was no other way to get them. I'm not sure if it's just me but most PC games don't seem to stay in print for very long in the scheme of things. I had a heck of a time finding a new Morrowind recently and even more trouble finding Oblivion. (I have bought multiple copies for friends over the last couple of years.) I also realize these are old games, but when I bought even older games - the Myst collection - THE only way I could get them without spending thousands of dollars was used via Amazon Market. This was the same with Beyond Good and Evil. I refuse to use Steam for a multitude of reasons so digital copies are not an option for me.
On the one hand, I like used games - they're cheap. (and, in the case of old games, frequently the only way you can find them)
On the other hand, I can totally understand the game publishers looking at Gamestop and thinking "They're making $20+ profit off each sale of a recently-released game, and we're not seeing a penny of it" and wanting to bang their heads against the wall. Yeah, some fraction of people buying used wouldn't have bought it at full. But you've got to believe that a decent % (especially among people buying released-this-month games used for $5 or $10 off) are honestly lost sales. It's completely reasonable that the companies would want to try to do something to grab back a share of that.
So... I like to frequent thrift stores and consignment shops. I guess Nike, Aeropostale, and every other company who's product I bought second-hand at a cheaper price should be getting a cut too huh? The only reason electronic goods are being treated this way is because they have the power - to a point - to restrict resale. If there was a way to restrict resale of clothing or furniture, I'm sure companies would try to do that too, they're all greedy. And gaming companies can continue to treat their consumers this way because the vast majority of those same consumers will just allow it to happen so long as they get to play the game of the moment.
Look at the over all quilty of video games in the recent years. For example Bethesda put way more time, thought, and effort into Oblivion then they did with Skyrim. Yet they wanted $60 for both ganes at release, and this happens with every developer. They are making less quailty games and demanding the same full price. Its no wonder why people buy and sell used games!

Umm... if you're going to compare Skyrim with any of the games in the TES series based on depth and quality, please use Morrowind. Since that game we've seen huge downgrades in the quality of the series.
I disagree. Bethesad put more thought into Skyrim than Oblivion. Just compare the huge mountains, rivers, forrest, weather effects ect, compared to Oblivions hills and flat land, that wasnt even handcrafted but was generated by a computer.
Oblivion had 1 dungeons designer, Skyrim had 8.
Skyrim may not be a huge jump in the TES series, but it certainly was more thought through than Oblivion.
That did have a little something to do with where the games were located in the TES universe. Skyrim is rugged and wild... Cyrodiil isn't.
Personally, I don't think I'll have to worry about the prices of games in the future. I don't agree with the shift in DRM over the last few years so I haven't been buying many anyways. ( I play mostly on PC. ) And console games are already too expensive as far as I'm concerned so I usually only buy one or two games, on sale and usually used, anyways. I can't afford to keep up with the ever increasing demand of machines, especially PC systems, so I rarely have a system that can run the new games anyways. I eventually "upgrade" to a computer that can run games that are about 5 years old. *shrug* Though I'd like to add that if Skyrim hadn't been attached to Steam, I would have happily - and still would be happy - to pay over $100 for a copy. But having Steam made the game worthless to me.
