Okay, well hear my reasoning, while it may sound silly it's just my opinion.
Well for one, when loyal nintendo fans were first out to buy the system, it was valued at around 300$
A well kept system, while used, if kept in great condition, within only a little over a years time, if the system is still being sold for the same value as when it was released
it should be still worth the same amount in value.
Nintendo on the other hand, after 6 months time, cut the systems value in half, thereby everyone that bought it before hand has now lost half the value in something
they paid money for gone straight to the hands of nintendo.
Nintendo in response gives us 20 free games, that not only have gone down in value over the years due to being outdated to make up for the loss that we paid for,
but in reality it was to shut us up and make sure they didn't lose loyal customers.
While I do think free of charge for a system upgrade is unrealistic, I think it would compensate for the 150$ in value you already have for a well kept system
but will also compensate for the price difference we originally paid for. While its an upgrade, it is NOT a difference in hardware, because it's the same exact system, just bigger screens, which is what I wanted from the beginning. This is just my opinion, just thought i'd share if to see if fellow members agreed or not.
