Playing Games to Save the World in the Apocalypse

I want to stay here until the end of the world! Play games forever! Playing games can also save the world! I'm more stubborn than you think! The only thing more fun than games is games! Let me finish the game Doomsday first! PS: This introduction of more than 100 words was written by a man than I expected, so it's just enough! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
