ok, let me offer a rebuttle for the above statement...
first of all, the license that you buy on your Wii is more limited to that what you get at a used game store. If you buy games online and download them...then get tired of them, you can't sell them. With a used game it has value and can therefor be sold again. As well as you can only play your VC games on the one and only Wii that you downloaded them to, i'll admit that isn't that big of deal considering most of us don't play retro games on different systems.
second is used game store can't make the games....as we all know. If they only released so many games on the system, the less there are the more valueble that game is, and as time goes on the stock pile of those games will only go down since they never make anymore. Not to mention that these games at used stores cost what they do because of course....they buy them from people.....so they have to of course charge even more than that to make a profit, again, we all know this....I'm not trying to say no body is aware of this but I only say this cause it brings me to the third.....
which is third, ALL money that nintendo gets from VC sales is profit....period. There is no cost of manufacturing or parts, and for nintendo and third parties, this is a second chance to make money on a product that is done and over. So to argue that Nintendo for some reason must charge near the same for them in a used store is stupid. From a marketing standpoint in my opinion, the best thing you want to do is sell it at the lowest cost possible that everyone is willing to pay. All you have to do is look at wal-mart and know that this method in fact does work.
So in my personal opinion, I do believe if you were to lower the cost of VC games, given the choice between used games and VC, I'm sure if the cost difference is fair enough rather than close to the same, people would go with a clear choice of downloading it at a lower cost. After all, I'm sure Nintendo would rather make some money than no money, cause of course they make no money if someone buys it used. Plus if you can get 2 games for 6 dollars, or just 1 game for 5. Clearly the 2 games for 6 is a win win situation, even though it's only a dollar more, you take and add it up and I believe they would make more money than their method currently.
