Super Mario Bros. Wonder devs created 2,000 game-altering “Wonder Effect” ideas

SAN FRANCISCO—When thinking about what makes 2D Mario games special, Super Mario Bros. Wonder director Shiro Mouri recalled the excitement he felt playing the original Super Mario Bros., discovering things like the warp zone and hidden vine blocks for the first time. Across decades of 2D Mario games with similar designs, though, it has been harder and harder to make a game that feels like it's "full of secrets and mysteries," as he said during a Game Developers Conference presentation this week.

"At some point, all of this has become normal," Mouri said of once-fantastical Mario game elements like mushrooms and coin blocks that have now become staples of the games.

Recapturing a world full of "secrets and mysteries" was the guiding principle for the development of Super Mario Bros. Wonder, Mouri said, but it took a while to figure out the new perspective necessary to get to that point. When Mouri prototyped an item that warped Mario to a new location, for instance, producer Takashi Tezuka said the effect "isn't so different from how it's always been. What if we changed the environment instead?"
