Mario steps out of the game and asks you what happens next. You're not watching a story unfold on a screen, you're deciding it, shouting answers into a plastic phone shaped like a mushroom, and the OVA actually responds to you. It's gimmicky enough to feel like a genuine artifact from the late 80s, but the comedy works because it trusts the bit completely. The real charm isn't the interactivity; it's that someone made a Mario adventure specifically designed for a kid to yell at their TV and feel heard.
Super Mario World: Mario to Yoshi no Bouken Land is a one-episode comedy OVA adapted from the game Super Mario World and built as an interactive video. It was made for Bandai's Terebikko system, where viewers answer through a microphone shaped like a telephone. Along the way the video poses multiple choice questions, such as guessing what will come out of Yoshi's egg.
