And again, though you may not like this approach (especially if you weren't a big fan of those assets from the get go), it's a sound response to the rise of iOS gaming, where development cost is low and free-to-play is the price to beat. A game like New Super Mario Bros 2 can be made inexpensively and quickly specifically because a large majority of its assets have previously been created, and due to this lower-cost production model, Nintendo can afford to sell this game more cheaply than it might sell a more elaborate "AAA" title. This approach allows the publisher to straddle that line between low-cost, throwaway smartphone games and more traditional "AAA" titles, thus ensuring that, even at a reduced price, game content can maintain some of the value that the iOS model has sapped out of video games. Additionally, regardless of how much effort Nintendo puts into 2D Mario, it's going to sell through the roof, so why not make it as inexpensively as possible? The profits from these titles allow the company to create bigger games on a larger budget, so it's hard to see low-cost, high-profit development as a bad thing when it serves the purpose of creation.
