DS Daily: Buy? Or sell?

Yesterday, in the "lolwut?" moment of November so far, we heard that Nintendo is making a game that will teach John Q. Public the ins and outs of the economy. Because Nintendo knows a thing or two about making games, we trust it will be an engaging experience, and the economy is something we'd like to be better informed about.

Then again, the subject matter also seems random, and something that wouldn't be overly useful to many DS owners. We can understand stuff like Professor Kageyama's Math Training (most of us use math every day, and increased mental sharpness with numbers is handy) and My Japanese Coach (Japan and its language are fascinating, and many gamers have an interest in the culture), but would you regard an economy-based training game as practical to your needs? Would you purchase it?
