Summary: BUYER BEWARE! You cannot delete pre-existing data from the cartridge, so if you buy a used copy there is NO WAY to delete the data. I searched all over the web and its unanimous that you cannot delete the data. Capcom did a similar thing with Resident Evil Mercenaries where you cannot delete the save data. Developers do this to try to cut their losses from the used game market. I bought this game used from a gamestop and returned it quickly.
Summary: The game is great, I mean the classic Monkey Ball-style gameplay is perfect and the controls are great... the only problem is the game is WAYYYY too short. I beat it in like an hour or something.
Summary: I know this game is three years old, but I feel a need to write this review because its average rating is 4 stars, while Banana Blitz has an average of 3. This may lead some people to think that the Super Monkey Ball series was revived with this game. This could not be more wrong. Here's my theory: Banana Blitz got poor reviews because fans of the GameCube games had high expectations of it. These disgusted fans decided not to buy any more Super Monkey Ball games.
Summary: Super Monkey Ball 3D is genuinely, without a doubt, the greatest game I have ever played. It has breathtaking visuals, EXTREMELY challenging and rewarding gameplay, a 60+ hour campaign and mini-games which play similarly to Super Smash Bros. and Mario Kart respectively, but in my opinion they're WAY better than either of those games! The game will keep you going for hours on end and you won't want to put it down, honestly one of the hidden gems of the 3DS library.
