Several people in my dojo has the Aikido3D and they absolutely love it! Amazingly I was the one that brought the information about this software before it came out to the dojo and yet I didn't purchase it.
I like the software. Excellent concept, well-executed.
The only complaint I have is not something most others would care about
: his Japanese pronunciation is so bad it constantly makes me wince.
Fortunately, 99% of the dialogue is in English, and his English is quite pretty.
Definitely recommend this as a reference work.
