    I understand this game is for an handheld, but WHY DID THEY LEAVE THE MIIS OUT?!! Other than that, it is awesome. They also need to add a frigging update that includes:
    -Miis
    -Story Mode Part 2
    -Dream Events
    -in-game Shop for DLC(characters,games,etc.)

    Worst Mario and Sonic game so far. The Wii version is way better. The great dream events were all thrown out. The story mode is not as good as the Wii. The Miis are gone too. WHY?! This 3DS game is a 5/10 only because the graphics are okay and it is at least playable.

    This one is not the Wii version, although they are usually mixed into one entity. However, this one tries to stand out from the Wii version, but it's a 3DS game, so people are gonna hammer it for 'not as good graphics' or 'my head hurts from the 3d', or 'it was made during the dark times wawawa'. But if you look past, you get a solid game.

    It is true that this game is not high quality 3D, of course, but the little that is new has some games, you type with your fingers!, Medleys, madness games (replacing London Madness) Thurs otherwise not bad ...

    Sega's intentions with this game were undoubtedly good, but the story mode is lacking and the mini game collections paltry. There are much better offerings on 3DS than this.

    Even though Mario & Sonic at the London 2012 Olympic Games is good looking and charming, it lacks severely in the gameplay category and no one will be able to have even a tiny bit of fun with these sports events.

    The choice of events is staggering, even if they're a bit too streamlined. [Apr 2012, p.88]
