Mario Tennis Fever is a sports/arcade game, so 'story' length is short and not the point. HowLongToBeat lists an average of about 5.5 hours to beat and roughly 14.5 hours for completionists. That headline figure essentially reflects the single-player Adventure mode, which reviewers finished in roughly 4-6 hours (GameSpot ~5 hours, TheGamer ~6 hours, some ~4 hours) and described as a long tutorial with mini-games. As a competitive multiplayer title, real playtime is effectively open-ended through Tournament, local versus, and online Ranked play.
