Superman, released for Nintendo NES in 1987, falls squarely in the action-adventure genre. Developed by Kotobuki System Co, the game allows players to control the iconic superhero across two realms - the bustling Metropolis, and the aforementioned 'Phantom Zone.' Playing as Superman, the gamers utilize his superpowers to combat foes, including Lex Luthor. The game boasts of multi-level action and a variety of gameplay mechanics, challenging the player's endurance and strategic planning. The graphics, while primitive compared to today's standards, strongly echoed comic book aesthetics.
