Ah, old cartoons. Good stuff.
What thread about old cartoons on an anime site would be complete without references to two of the greatest 80s cartoons ever, Robotech and Voltron? It wouldn't be, which is why I have remedied it.
For the record, I speak of Lion Voltron, not Vehicle Voltron.
As far as American cartoons, I was a fan of GI Joe and Transformers as well, and I liked Darkwing Duck. Thundercats was okay at times, but Snarf was irritating.
For video game cartoons, I watched the Super Mario Bros. Super Show (which showed Zelda on Fridays).
*starts singing* DO THE MARIO!
Super Mario Bros. 3 was decent, but not quite as good. Super Mario World fell flat, because the music was bad, there was too much of an attempt to make it like Flintstones, and they never DID say what happened to Toad.
I'm sure there's many, many more, that I have somehow forgotten, and am ashamed of that. So I shall depart now.
