Important thing is to remember that Real and Super come from SRW, and are more a method of classifying what the mecha
are than the tone of the series; it's just that Gundam and its numerous clones and progeny tend towards one thing, but, well... G Gundam is still Real (barely), and Evangelion is still a Super Robot series, because enormous cyborg alien
things and more of a MotW scenario than conflicting sides...
Also SRW tends to de-angst Shinji and then Evangelion loses all Real links at all.
Gunbuster was the biggest mecha for its time. Later, Gainax one-upped it with Diebuster, and later still they did TTGL, and then STTGL. XD
