Some shows I'm currently watching that would probably bump out the bottom of my current list would be:
Legend of the Galactic Heroes.
Kaiba.
Hellsing.
Hajime No Ippo.
Slayers.
I've become a bonified gamer since last commenting on this thread as I've been really getting into Metroidvanias. My favorite game and one of my favorite pieces of media I've ever consumed is Hollow Knight. which is pretty much a perfect rendition of the Metroidvania genre. Other great games I've played in the last few months have been Salt and Sanctuary which probably has the most versatile and satisfying combat system I've ever experienced and Axiom Verge, another metroidvania I think gives the games its paying homage to ( Super Metroid ) a run for their money.
