Mario Tennis Aces is a sports title developed by Camelot Software Planning, released in 2018 for the Nintendo Switch. The game centers on competitive tennis matches featuring Mario and a roster of varied characters, with mechanics that emphasize reading opponent positioning and shot selection to gain tactical advantages during rallies. A notable addition is the return of a full story mode — the first in the series since the Game Boy Advance entry — which structures its tennis gameplay around missions and boss battles rather than straightforward competitive play. This adventure component gives the title a dual identity, blending traditional sports competition with goal-oriented single-player content. The combination of refined court mechanics and a substantial narrative mode distinguishes Aces from its predecessors and positions it as one of the more feature-complete entries in the long-running Mario Tennis series.
