Space Channel 5 was released by Sega in 1999 for the Dreamcast, a rhythm game in which reporter Ulala dances to save the galaxy from an alien invasion. Its mix of music, dance battles and bright science-fiction style made it a cult favourite, and later ports and a virtual-reality sequel kept Ulala in front of new players. Short clips from the game still circulate online because they instantly recall that playful era of console gaming, when rhythm games felt fresh, colourful and deliberately over the top.
