This isn't the crossover that you have been waiting for. This is "Mario Party with Sonic & Friends."

User Rating: 3 | Mario & Sonic at the Olympic Games WII
Expectations for a game featuring two of the most iconic video game stars can be relatively high. Despite the iconic crossover, Mario and Sonic at The Olympic Games seems like an afterthought. And in that afterthought, someone decided to add some horrible, almost broken gameplay mechanics to make a bad idea even worse.
Mario and Sonic's presentation is one of its main problems. The game feels lifeless, with bland visuals and silent crowds. Even with other players in the room, Mario and Sonic feels like a birthday party, just without the excitement and cake.
The gameplay in Mario and Sonic is an absolute nightmare. Not only are there many boring mini-games, but these mini-games can easily tire anyone's wrist. The motion controls are very gimmicky, with games only involving "waggle fests" with your wrists. The "career" mode is only a string of events, with nothing interesting to present, other than event after event. . Earning gold medals in events isn't rewarding enough, giving only unlockables about the "history" of Mario and Sonic. The extras won't engage players to complete everything. Things get really tedious, really fast, and even the most hardcore completionists won't want to replay any of the events to receive a higher score. There
Mario and Sonic at The Olympic Games isn't what everyone expected. It sounded like an ambitious project, but in the end, Mario and Sonic is just a tedious, lifeless game that shouldn't be played. If anything you will just hurt your wrists while playing.
