Terraria, like Minecraft, has made quite a splash with players who like to create entire worlds out of seemingly simplistic building blocks. It came out on 3DS last year thanks to 505 Games, but in Japan, Spike Chunsoft is handling the publishing duties.
Perhaps sensing a Minecraft-style smash hit, the publisher has produced a 15 minute video which attempts to explain the core mechanics of the game, and - as is usually the case with these kind of videos in Japan - employs an infectiously enthusiastic female presenter to do the demonstration.
Have you taken the plunge with Terraria on the 3DS? Or are you waiting for the Wii U version?
