Since I'm a mecha head I would have added Getter Robo and Mazinger Z and their respective movies. I think american kids would have been responsive to super robot shows like this since Gundam Wing cleaned house when it debuted on the programing block.
I wonder if the 2002 Hunter x Hunter series could have been brought over too.
Was the old HxH any good? Big fan of the later reboot but I've never watched the original or the OVAs.
I heard good things about them and the ovas.
