Someone clearly put a lot of time into creating the Rosetta Stone program. The production values are pretty good. But, the purpose of the program is to learn Japanese, and the amount of Japanese you can learn from all three programs is very limited. Better to spend the money on covering more material, and skip the bells and whistles.
In my estimation, all three programs are insufficient to equal even one full year of college Japanese. I'm not saying that the program is bad, just that it is limited in the amount of material covered. Perhaps my expectations were too high, but given the shockingly high price, I think I had a right to have those kinds of expectations. I would have returned it if I could, but I foolishly bought it on sale when it cannot be returned.
