I know a few people who could use a bit of training in business etiquette (and, no, I'm not naming names). Unfortunately, I don't think said people own a DS. Oh, well.
This is definitely one of the thousands of "training" games taking over Japan these days. What's up with that anyway? I guess Japanese people really like to learn about things. What an interesting contrast with the U.S. Here we'd rather blow things up (especially people). "Learning? Yuck! What are you, a fag?"
