Summary: I haven't really been that up-to-date with the Super Monkey Ball franchise, since the only other two games I have of the series are Super Monkey Ball 2 and Super Monkey Ball Jr. Both of which I did not really play too much. Then again, I haven't played them in a while, so maybe my experiences with them may change if I get back to them, but I recall them giving me a pretty hard time with their stage designs. So is it just me or is Super Monkey Ball 3D easier?
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.
