The surreal, colourful Katamari Damacy is 20 – and still the weirdest game I have ever loved

This wacky Japanese game leaves a lifelong impression on everyone who plays it, if only because they can't get its theme music out of their head

My parents were somewhat sceptical of video games when I was growing up. I did have a SNES and then an N64 as a child, but I was allowed to play them only at weekends, so on Fridays I would come home from school and binge on Mario 64 with a huge pack of Haribo Tangfastics. My gaming horizons didn't broaden until I was a teenager, when I started earning enough of my own money to buy myself a PlayStation 2 and I started hanging out on forums with other nerds whose gaming worlds were significantly broader than mine.

And the PlayStation 2 had some weird games. The N64 did to an extent - I nurture an enduring fondness for Mystical Ninja Starring Goemon - but not like Sony's console. There was Dark Cloud and Monster Hunter, Yakuza and Mojib-Ribbon, God Hand and kami and Ribbit King, which is still, as far as I know, the only game about frolf (frog golf).
