Quote from StephKuran
The thing is that Last Game was supposed to be a short story, but as I read it had great success so the author decided to make a serialized story.
I'm pretty happy, and yeah, this happens a lot. I don't recall some right now, but famous mangas came from oneshots.
Well here are some
Well Bleach, Naruto, Nisekoi, and TWGOK all started out as oneshots, and if you could see those oneshots most were terrible (in comparison to their serial), except Nisekoi's, TWGOK's was just a little poorly drawn. Even Usotsuki Lily was created from 4 seperate one-shots. but I digress
I passed over this series originally because it was completed, and assumed it wasn't good since it was only 4 chapters, which usually means it was a manga that tried to serialize but failed.
I do find it interesting it is told from the guy's POV.
