Mario Kart is one of the cruelest games in existence. With the exception of maybe Mario Party, no game is better at making you feel accomplished and skilled before ripping it all away from you with sheer happenstance. Oh, you've been in first place for 2.95 laps? Here's a red shell that knocks you into a banana peel, which knocks you off a cliff, which puts you in 7th place. But if you think playing the game is foul, think about what the characters are going through. When you think about it, they commit acts much more heinous than tossing a blue shell at the last minute.
