Mario & Sonic at the London 2012 Olympic Games delivers a colorful and energetic collection of Olympic-themed minigames featuring beloved characters from both franchises. The variety of simplified sports events offers quick, accessible fun, especially in its multiplayer party mode. Dream Events add a whimsical twist to the classic sports formula, injecting a burst of creative chaos. While it lacks a compelling single-player experience and some events feel overly simplistic, Mario & Sonic at the London 2012 Olympic Games is a solid pick for casual gatherings and fans of zany multiplayer action.
