Poor Tournament Seeding
Typically, your average open will have the following events: men’s singles, men’s doubles, women’s singles, women’s doubles, and mixed doubles. In Mario Tennis Aces, Peach may find herself in a bracket with Diddy Kong, Toad and Bowser. Congratulations on qualifying for the Mushroom Cup, young lady! Hopefully, your training has prepared you for the possibility that you may someday have to defeat a monkey, a sentient fungus and a fire-breathing turtle of death. It sounds more like a hallucination dreamt up in Trainspotting than a legitimate tennis tournament.
To further complicate matters, some of the players have identities so ambiguous, you can only respond with a bemused shrug. Does a Spike have a gender? Does a Chain Chomp? Does a Luigi? Nobody can say for sure, and it sends Vegas into an absolute frenzy. The betting sheets are a frenetic crapshoot where the only certainties are that rules are going to be broken, and Mario is going to be one of the finalists. As a result, his payout is actually -3% of your initial bet. Safe odds, but not exactly a lucrative result.
