Pushing Buttons: I went to Japan's Nintendo theme park – and it was a childhood dream come true

I've always written about the intersection of games and real life – that's where the interesting stories are often found – but rarely do I get the opportunity to do so quite so literally as I have this week. Yesterday I visited the Universal Studios theme park in Osaka, where the world of Mario has been reconstructed in the real world. You walk through a green warp pipe and, when you come out the other side, through Princess Peach's castle, you emerge into a primary-coloured, crowded Mario-scape, all green grass, yellow blocks and brown brick, with critters moving back and forth across banks of question-mark blocks and the yawning maw of Bowser's Castle across the way. I've been dying to see this Nintendo theme park since it opened, but I wasn't prepared for how impactful it would be to walk into a physical manifestation of my eight-year-old self's dreams. Super Mario World is constructed in such a way that you can't see the outside world when you're in there, helping you to disappear into the fantasy.
