It's a balancing act when it comes to budget and parts breakdown. There is a lot of cash for each piece that is tooled.
Have you seen what Bandai is doing with Space Cruiser Yamato 2199? The kits of the updated ships look amazing. It almost makes me wish they would do an updated version of the original Macross. I just finished watching it again. The animation is beyond rough. Southern Cross has better animation. Terrible mecha design, but better animation.
I have unbuilt kits of all four ships. I'll have to bust out the epoxy putty when I get around to doing them.
