Short Gameplay: Rockman Mega World (Mega Drive)

Mega Man: The Wily Wars, released in Japan as Rockman Mega World is a video game compilation by Capcom for the Sega Mega Drive. The game features remakes of the first three Mega Man games (Mega Man, Mega Man 2, and Mega Man 3) that were originally released for the Nintendo Entertainment System, and is a pseudo-sequel of sorts for these titles. The Wily Wars was released in cartridge format in Japan and PAL regions. The North American Genesis version was available exclusively via the Sega Channel service.
