Sounds like I want you to list your 20 favourites right?
Well in one way thats spot on.
But I wanna know from a REAL veteran what 20 animes / mangas (I dont mean 20 of each but a serie might be better in the manga then the anime and the other way around) I NEED to see / read before doomsday!
You don't have to list em from nr. 1 - 20 depending on how good they are, bascially I wanna know something around 20 series of ANY genre, the very best there is, and I'll watch em all and smile over how right you where.
I've watched a lot anime but I dont feel that the lot of them are amazing throughout the whole series...
