I'm normally the kind of cynic who rolls her eyes at gimmicky marriage proposals. But there's something about the strict attention to detail in this one that begs to be admired. Anyone who replicates Mario's pastoral world on his living-room walls deserves to find his princess. Turns out she was in his castle all along. Also note the background music and light-up fireworks.
It'd be interesting to see other video-game landscapes translated into romantic settings. I'm thinking Donkey Kong Country and Pac-Man's dot-and-fruit-littered world. Though somehow I don't think Grand Theft Auto's urban wastelands would fit that bill. Unless, of course, you looted the ring.
