No bashing others' opinion(s)
--------------------
If you could choose only one anime where all the episodes that will ever be made are mailed to you for your viewing pleasure only, and anybody else trying to watch them would see nothingness, which one would it be? Perhaps give a reason as-well.
By ever be made I mean episodes that have already been made, episodes that are just in concept, and episodes that will be made in the future that haven't even been thought up yet. Lets just say you somehow got them from the future.
--------------------
I would choose either Fairy Tail or One Piece.
Reason: Fairy Tail & One Piece are both anime that I'm rather interested in, and from what I can tell they will both go for a long time. I would add Ao No Exorcist in it however it's still in it's young ages and it very well may not continue past 26 episodes but one can hope.
If you haven't seen them, you should check them out! I know One Piece can be intimidating to catch up with, though.
