You know what else is amazing about all those commercials? They all had release dates. What a concept to let people know, if the game is not out already, when they can pick it up.
When I saw the retro ads section, the first one I thought about was the disgusting Yoshi's Island ad that had a man eating tons of stuff and exploding. Somehow, I bought that game despite the ad, and I'm glad I did. Virtual console, Nintendo?
To me, the "I wouldn't have bought it anyway" argument doesn't make any sense. First of all, the very fact that you downloaded it shows that the item had some value even if that value wasn't "full price". Many games may be overpriced, but the the market will take care of that problem. If a game truly is not a good value, the publisher will adjust the price to sell more copies. Maybe that lower price would have made it so you did find it a good value, but then you would not buy the game because you already have played it. In the entertainment industry, like most other industries, there is a general principle that things are going to be more expensive when they are first released. There is a premium to have earlier access to something than some other people. Ultimately, it is up to the companies to set the price at the correct point. That's not to say that consumers have no influence
Second, people say that pirating games they wouldn't have bought anyway isn't really costing anyone anything, because they still will be buying the games they would have bought. Unfortunately, this is not true. While you may not have bought that certain game (although maybe you would have if there were no other alternative), you are still using your leisure time on that video game. Assuming you would play video games for about the same amount of time either way, any time you use on a "free" game is time not being used on a game you would have bought.
Last, the people do it because they think they are entitled to try the product before they buy it. I understand that trying a game is important to many people before making a $50 or $60 purchase, but that does not entitled you to break the law to try a product. Again, it is up to the companies, with pressure from the market and consumers, to provide consumers with a meaningful chance to try out their product.
I think the thing that concerns me about IP infringement is it seems to have created an unwarranted sense of entitlement. A lot of people are saying that because they can't afford all of the games they want, that justifies them violating someone else's copyright. Also, they might not have bought the game for $50 even if they did have the money because it was not worth it. It seems to me that things such as games and other entertainment are luxuries and if you cannot afford them or don't want to pay, then you are not entitled to them, regardless of whether they are tangible or intangible.
As for other problems that people have with the current system, such as Digital Right Management or just copyright in general, that does not entitle you to pirate either. If you have ideological problems with the way things are, you try to get the business or government to change their policies and you choose not to buy things from companies you have problems with.
