That's a horrible excuse.
this all reminds me of the road Final Fantasy went down. it started out as a story driven franchise that happend to have nice visuals. Now-a-days everything becomes secondary to the eye candy.
How the heck does that analogy apply to Macross Zero? So far the Mac 0 story is totally character driven, despite all the pretty CGI.
bsu legato's point is very valid. A VF-1 in full CGI would look way more advanced than the AnimeFriend shots everyone seems to use as their basis of comparison between the two shows. Not accepting the advance of technique and technology between two show 20 years apart is no reason to invent this silly theory the VF-0 is more advanced than the VF-1. They said in the show itself that the VF-0 doesn't even use the OverTechnology engines of the VF-1. The official stats so far indicate the VF-0 is inferior to the VF-1, showing the VF-0 is both heavier and slower than the VF-1.
I personally don't understand how so many people have a problem with the VF-0 compared to the VF-1. The VF-0 fighter mode looks a little more aerodynamic than the VF-1, but the VF-0 battroid mode looks like a clunker in comparison the the VF-1.
If the mecha in Macross Zero looked like the YF-19 or YF-21, there would certainly be a reason to cry and shout. As it stands, the VF-1 and the VF-0 are the two most similar looking, different-model Valkryies that Kawamori has ever created.
