I had been wanting that game for a couple of weeks since I bought Fuun Takeshi Jou (Takeshi`s Castle), the first of the two games in that series at a shop here in town.
The games feature similar challenges as those on the TV show. There is a pretty good review of the first one on Pink Gorilla here. They were also featured on an episode of Game Center CX at one point.
You might wonder how I enjoyed them. Unfortunately I haven`t been able to do so. Perhaps my predicament is best described in the following mathematical formula:
Overcrowded Japanese apartment

Dog who LOVES to do nothing but bite feet all day

Not a good environment for Family Trainer games

So basically my Family Trainer pad has been sitting in its box collecting dust ever since we got the little guy. Someday though I am going to break that thing out and give these a try.
Incidentally if you are interested in getting a copy of the first of these games, go check out Manuel`s shop (linked above). He has the most reasonably priced copy of it you are ever likely to find, and he is a great guy to be buying stuff from to boot!
