The Creature That Ate Sheboygan (1979)

A fabulous game where one gets to "wreak havoc with the monster of your choice". You design a monster (Godzilla, Mothra, The Really Big Slug, etc.) and then try to destroy as much of Sheboygan as possible; the opponent scrambles civilians out of the way, then sends in the police and eventually the Army. Great fun!

Spawned numerous imitators, such as the old Epyx computer game "Crush, Crumble & Chomp", or more recent games such as "Super Giant Monster Showdown".
