Armitage III has been released in two forms. A four part series, and a full length movie. Each of them have some additional parts to them. The main difference is the voice actors. For the movie Polymatrix, a few more well known people were made the voices (although their voice acting talents leave something to be desired in my opinion). Although my personal preference is the four part series, my wallet (which has chronic money deficiency syndrome) tells me that it would probably be better to buy one video for $19, rather than four individual. Either way, the general gist of the story comes across.
