Exciting Hour was released in October 1985 by Taito under license from Technos.
This game is known outside Japan as "Mat Mania - The Prowrestling Network
A 2-Player version of this game is known as "Mania Challenge
In the game, if you look closely at the audience in the background, you will see a variety of recognizable characters including a boy in a Union Jack t-shirt, Darth Vader, Superman, the Stay Puft Marshmallow Man (look to the far left when outside the ring) and ZZ Top is very prominently present in the middle of the crowd.
In the game :
TWA stands for Technos Wrestling Association.
Insane Warrior's name is misspelled as 'Insane Worrier'.
Coco Savage's name is misspelled as 'Coco Savege' at the top of the intro screen, but is spelled correctly in the announcer's scrolling message.
The Piranha's name is misspelled both at the top of the intro screen and in the announcer's scrolling message as 'The Pirania'.
Blues Bloody, the champion in this game, is very obviously a copy of Hulk Hogan. Other wrestlers are copied from superstars of the early 80s: The Insane Warrior is a copy of Road Warrior Animal, Coco Savage is probably Kamala The Cannibal and The Piranha is probably Mil Mascaras. The main wrestler ('You') bears a striking resemblance to Kerry Von Erich. These are guesses, but all the mentioned wrestlers were very popular about the time this game was released.
