The red plumber has provided us with a lot of entertainment over the years, but there's no denying that the worst Mario games are some of the most dull and boring video game experiences of all time. It's not often that a bad Mario game comes out, but when it does, it's disappointing to see such an icon of gaming get dragged through the mud.
Do any awful Mario games immediately come to mind? Mario Is Missing! for the SNES is easily one of the worst Mario games ever made. This educational game has the player control Luigi after Mario is captured in Bowser's Antarctic Castle. Mario Teaches Typing is another horrible Mario game that almost no one remembers from the '90s, as is the dreadful Hotel Mario. Other Mario games that often get hated on are Mario Clash, Mario Party 9, and New Super Mario Bros 2.
Vote up the terrible Mario games on this list that you feel deserve to be called the worst of all time. If you disagree with a game being bad, downvote it so it falls to the bottom.
