YMMV / Mario Sports Mix

  • Crowning Music of Awesome: For starters, there's the Starman theme, the Star Ship, and Bowser's Castle.
  • Funny Moments: The press conference.
  • Game Breaker:
    • Moogle's Limit Break in basketball. The ball may or may not disappear mid-shot and, if it does, it reappears at another angle of the basket. Usually, it's not that difficult to deal with if you cooperate with your teammates... except if Moogle decides to make the ball disappear twice. Then, when it respawns, it's a tenth of an inch away from the hoop, leaving you with a near 0% chance of blocking the shot. Have fun!
    • In dodgeball, some players have come up with a way to use the ball while on the opponent's field. The key is being in mid-air so you don't automatically lose possession of the ball, which only triggers if you're touching the ground. This significantly improves a player's chance of offense when they're supposed to be vulnerable, and it soon became a key element in the metagame.
    • Bowser Junior's Limit Break in volleyball and dodgeball. In the former, if the opponent manages to receive the ball, Junior just has to approach the net, jump and spike the ball immediately at an uncovered spot after his teammate has received the free ball from the opponent. The other team will not have a chance to receive this time, because they will still be sliding through the field randomly, and the ball will have much more speed. Of course, this involves the player's knowledge of another Game Breaker in volleyball: spiking at will, anytime, by pressing A in nunchuk control style. Now, in dodgeball, even if the opponents dodge Junior's attack, whoever's at the "prison" behind the opposing field can catch the ball. The player just has to take control of that character and throw the ball again when a sliding opponent comes nearby.
    • Any luck-based Limit Break can be considered this, especially when used in a critical situation. For example, being two points behind in basketball and performing Ninja's Limit Break as a buzzer beater to win. Good luck stopping him if you're on the opposing team.
    • Using items when spiking the ball in volleyball at Peach's Castle. Normally, your window to pass the ball is limited by the water streams, but you can get the ball through them with any item. It becomes the key to winning in that arena. Of course, you can also do the opposite: spiking at the water curtain so you can easily receive the ball in your own field and charge up your Limit Break. As long as you don't spike it across the net, you will be able to repeatedly fill up the gauge.
    • Cactuar's ridiculous speed. It's the key to winning in basketball. Heck, even using his Limit Break to incapacitate people while you travel across the field easily makes things laughable. No wonder there was always a Cactuar in competitive play online.
    • Black Mage's "dive" move in V-ball. It basically can receive any ball in any part of the field as long as it's not a superspike made by a power character aimed at the opposite corner where the mage is. Games can be dragged on for quite a while if you have a good defense as well and neither team can score. Now imagine a game between two Black Mages...
    • Now for the other mage. The white one. She can create a pretty large deflective wall in volleyball that cleanly blocks any spike, even Yoshi's high as hell superspike! This protects her from being knocked out by any item or powerful superspikes. The timing for setting up the wall is pretty smooth and easy to get as well, as opposed to the hard-to-master Black Mage's narrow lightning. She can even set up the wall on the net's opposite end to the one she's at!
    • Any Limit Break in volleyball can come across as a Game Breaker when the ball is one tenth of an inch from touching your ground because it flawlessly gives you the ball back wherever it is wherever you are.
    • Luigi's Limit Break consists of sucking the opponents with his vaccum cleaner. There's an excellent chance all opponents will be knocked out if you wait until the very last second to score. The only thing that diminishes that chance is running in the opposite direction where Luigi is, but, even if the opponents do so, they will most likely still be KO'd. Scoring can get ridiculously easy most times.
  • Scrappy Mechanic: Having to unlock everything within each sport individually, meaning you have to unlock everything four times (except for Sports Mix mode) for 100% completion.
