It's far too easy to forget what it's like to be a kid. But one secret to happiness is to be able to pick out links to our childhood in the mundanities of adult life. That's why I love Mario Kart. Whether I'm imagining wading through frosting in Sweet Sweet Canyon to take a bite of that giant donut, or picturing myself, shrunken down, making my way through Waluigi's pinball machine, there's something rejuvenating about the game that provides a nice reminiscence of the halcyon days gone by.
