"We presume the cause of death was heart failure stemming from exhaustion," a Taegu provincial police official said by telephone.
Lee had recently quit his job to spend more time playing games, the daily JoongAng Ilbo reported after interviewing former work colleagues and staff at the Internet cafe.
After he failed to return home, Lee's mother asked his former colleagues to find him. When they reached the cafe, Lee said he would finish the game and then go home, the paper reported.
He died a few minutes later, it said.
Quick, we need to put an end to this! We need to sue the game manufacturer for making the games so fun, so addictive, that a 28 year old man literally PLAYS HIMSELF TO DEATH!! Get Congress to investigate this to ensure that this menace does not advance to our shores!!
