Scorched Earth (1991) is an old two-dimensional 256-color DOS game, but it might just be the only game of it’s era that is still enjoyed by many (including via many games over the years that have copied the gameplay). Up to to 10 people can take turns blowing each other up on one computer, and any or all of the players can be computer-controlled. Strategically buy various weapons and shields as you gain money after each round by destroying other tanks. The version I played used beautiful photographs for the fully-destructible terrain:
