Gah, I feel like one of the uninitiated now. I only managed to get 34/50 on the quiz and swore forwards and backwards that the getter robo clue was Dancouga for some reason. The Evangelion clue was also pretty damned inscrutable "Shogouki" does not scream Evangelion to me.

Cybuster had me putting in all the OVAs and series for super robot wars animations before I just gave up and gave myself the point for it.

I will say that is a LOT of mecha series though.
