The worst Mario game ever.
Gameplay: This is the real poop for this game. Like the title suggests, Mario gets missing. You play as Luigi, Mario's younger brother. He has to go in a castle and choose a door to go in. Each door represents a city. In a city, you search for clues for where Mario is. You'll spend most of the time roaming around in a city, being so bored, you'll drop the controller and go to sleep. Worst of all, roaming around is so repetitive. Nice job, Software Creations and Mindscape. (Note: Sarcasm)
Graphics: This is the only good part of the game. I like the SMW sprites, and the backgrounds are decent.
Sound: The game does have SMW sounds, but blended together with bland music.
Value: Due to the game's repetitive and boring gameplay, there is no replay value here.
Tilt: Overall, Mario is Missing is the worst Mario game ever. The game is super-repetitive and incredibly boring, and the music is dull. Avoid this abysmal game at all costs, and go spend your cash on another Mario game.
