First of all, Sigma six is the anime version of G.I. Joe. The only reason why this G.I. Joe is not that patriotic is because this one tries to make an appeal to all audiences especially now that USA is such a diverse country. They still want to stick to the high tech gadgets and team work. Sigma six has a lot of 3D effects that have never been used in G.I. Joe. Voices are okay but many of the voices come from Yu-Gi-Oh and Pokemon.It is 4kids so, what do you expect? For example Eric Stuart also does the voice of Brock(Pokemon)and Seto Kaiba(Yu-Gi-Oh) If you like anime+American army fighting this show is for you.This is nothing compared to the original.
