My Personal Reckamendashuns:
- - Holy Shit. Imagine Game of Thrones as an anime and the Lanisters are now giants that eat people.
- - Took me awhile but I found a Gundam series that I liked.
- - Sort of a cross between your typical "Everyone's stuck in a game" and The Hunger Games, except they're not actually in game.
- - I watched all the others, I have to finish it...
If you're into other things that are not anime:
- Young Justice
- The Venture Bros.
