Anime idea:
An anime where an otaku nerd is waiting in line at a convention and he dies because a big guy in the line before him falls over and crushes him.
He wakes up in an isekai fantasy world where everyone is an owl, and they call peck him constantly until he dies again. The end.
It’s going to be bigger than Dragonball Z
Anime set in a world where one form of competitive game is like 80+% of pop culture, like Duel Monsters in Yu-Gi-Oh!, Beyblades in Beyblade, racing in Initial D, etc. Chosen one underdog prophecies, rivals turned allies, high stakes matches with millions and/or the fate of the world depending on the outcome of the game, etc.
Except the game this world revolves around is high stakes tic tac toe.
Played 100% straight. Well animated sakuga shots of the protagonist drawing an X, with dramatic music and flashbacks to their childhood, etc.
No-one ever questions the fact that the fate of the world is hinging on high stakes tic-tac-toe. The protagonist goes from an impoverished amateur street tic-tac-toe player to becoming the national champion, defeating Old Testament demons, a megalomaniac billionaire, a fascist dictator, Lovecraftian horrors and rogue AIs throughout the seasons, saving the world multiple times. Through winning tic-tac-toe.
Does the stalemate issue of tic-tac-toe ever get addressed?
