The Blue Shell makes Mario Kart but in Mario Kart Wii, the Blue shell appears too frequently, it makes you go all the way back to 7th place and lowers your star rank. Mario Kart DS had a ranking system but it was just a skill indicator and didn't affect the game, whereas Mario Kart Wii requires you get 1 star rank on specific courses to unlock new bikes and characters-note that even people who are good at Mario Kart struggle to get 1 star due to the harsh AI and the biggest indicator of all, so how is a five year old going to manage! Fault 4 The biggest indicator of all in the last section drives hate and fear into every Mario Kart racer to have ever existed, yes, it's that peice of flying Blue overpowered peice of doom called the Blue Shell. Fault 3 The star ranking system on this game is harsh and competitive, Mario Kart was never meant to be really competitve because the whole point was to win. Being fair though Koopa cape and DK snowboard cross have really good music. Not only that, there are a couple of notes at the start of a course on the first lap, they used to do this on the 3rd lap as well but in the Wii version they don't. Fault 2 Fault 2 is the dreadful music given to some of the new courses such as the new Bowser's castle where the music is almost muted and maple treeway (which the music is absolutely terrible for the course). To be fair though, the coin battle is better due to the fact that the AIs actually go for the coins. On the Wii version however, popping an opponents balloon would give you a point and when all the opponents balloons are popped, they lose a point.
Fault 1 The biggest fault in Mario Kart Wii is the multiplayer mode-namely the balloon battle in the Mario Kart predecessors such as Mario Kart:Double Dash the balloon battle was all about popping the opponent's balloons and when all the opponent's balloons were popped, the opponent would be eliminated from that round.
Unfortunately, the worst Mario Kart Game ever made, even though all the faults circle around little aspects of the game.
