Other patrons initially thought he was sleeping, but when an employee realised he was not breathing he was rushed to hospital, where he was pronounced dead, the Taipei Times reported.

Doctors confirmed he had suffered cardiac failure, ruling it a "sudden death" from prolonged computer gaming, the report said.
