There are a lot of things I'd blow my money on if I ever won the lottery. A PC Engine LT would be one such thing; a copy of All Night Nippon Super Mario Bros. would be another.
Also, I'd buy every game-inspired t-shirt that caught my eye--with t-shirts bearing the designs below (created by artist Glen Brogan) being among my first post-lottery purchases.
The top design is called "Bottled Fairy," by the way, while the bottom one is called "Great Shelled Dragon."
If you've already won the lottery and you'd like to add either or both of the above-mentioned shirts to your wardrobe, pay a visit to Brogan's Split Reason store.
