Showcase: Matt Reedy's Little Golden Manga

I'm far from the world's biggest anime fan, but these three rank amongst my favorites. Just started Attack on Titan and I have to say that I'm impressed so far. The Titans are far less adorable than Matt Reedy presents them, though. They're actually pretty horrifying.

Showcase: Mario! Mario! Mario! by Joao Victor G. Costa

"Super Mario World" (1990)

Joao Victor G. Costa has redesigned the sprites for some of Mario's earlier appearances, and they're excellent. I would (re-)play all of these.

Forgive the quality of the blown-up .gifs... I wanted to share these in all their glory and no higher-quality versions seem to exist.
