Letting Everyone Know It Was A Good Mushroom

Iwata What were your initial considerations when you began working on Super Mario Bros. for the Famicom?

Miyamoto After Mario Bros., there were a fair few jumping-style games released by various companies and I felt that this kind of jumping game had been our idea.

Iwata Donkey Kong involved jumping, as did Mario Bros., so you felt that Nintendo were the real originators of this kind of game.

Miyamoto I did. I went as far as thinking that jumping is an original idea and that it should be patented! Anyway, I thought: "Right, I'm not going to let those other games top us!" (laughs) We had done tests where a large character jumped around with the blue sky in the background…

Iwata Video games at that time usually had a black background.

Miyamoto Video game designers back then wanted to keep that black background as it was less tiring for the players' eyes to see. But I felt like the time had come when people were tiring of that and I thought it might be good to have a primary color background that varies. So we utilized the technical capabilities of the Famicom to the full and decided to make Super Mario Bros. based on the concept of having a large character that would negotiate land, sea and air.

Iwata The game takes place on land, sea and air, with underground sections as well. Had you decided right from the start that it should be a large character that negotiated this terrain?

Miyamoto We had broadly decided on this approach. A large character that would run around on the ground…

Iwata …And swim in the sea.

Miyamoto 16. In terms of the game's structure, the swimming part is Balloon Fight

Iwata 16 The arcade version of the action game Balloon Fight was released in 1984 with a version released for the Famicom in Japan the following year. You're right. That's exactly what it is.



Miyamoto With Balloon Fight launching previously, that system of controls had been tried and tested. For the sky, we had the image of Sun Wukong from Monkey King jumping between clouds.

Iwata And what was behind the idea of having a large character?

Miyamoto We started off by doing tests to see how it would feel for the player to control a large character, double the size of Mario. As it felt really good, we continued to develop the idea. But then we discovered that it was more satisfying if Mario only increased in size partway through the game, so we decided to make a small Mario as well.

Iwata By collecting a mushroom, Mario increases in size to become Super Mario. But why a mushroom?

Miyamoto Well, the mushroom… When you think about Wonderland, you think about mushrooms, right? (laughs)

Iwata (laughs)

Miyamoto Some time ago I was being interviewed and I spoke about Alice in Wonderland. But it seems there was some misunderstanding and it's since been stated that I was influenced by Alice in Wonderland. That isn't the case. It's just that there has always somehow been a relationship between mushrooms and magical realms. That's why I decided that Mario would need a mushroom to become Super Mario.

Iwata The mushrooms don't just sit there, but actually move. What gave you that idea?

Miyamoto Well, in games you can either have objects following you that move at the same speed as you, objects that follow you but are a little slower than you, or objects following you that are a little faster than you. That speed makes all the difference in terms of how fun it is. We repeatedly did trials and saw the results, and I was adamant that something that you really want is escaping you at a bit slower speed than you would be really fun.

Iwata You can experience the enjoyment of chasing something.

Miyamoto Right. There was one problem, however. When you play, you encounter a Goomba right at the start and it's shaped like a mushroom.

Iwata It does look very similar.

Miyamoto So when you hit a box and something that looks like a Goomba pops out…

Iwata You run away.

Miyamoto Right, you run away. This gave us a real headache. We needed somehow to make sure the player understood that this was something really good. That's why we made the mushroom approach you.

Iwata Yes, that's right. If you play the game for the first time with no prior knowledge, you're going to run into the first Goomba and lose a turn.

Miyamoto Right, which is why you have to teach the player in a natural way that they need to avoid them by jumping over them.

Iwata Then when the player tries to jump and avoid them, there are going to be times when they get it wrong and end up stamping on the Goomba. By doing that, they learn in a natural way that by stamping on them, you can defeat them.

Miyamoto As long as you stamp on them, you have nothing to fear from Goombas.

Iwata But if you avoid the first Goomba and then jump and hit a block above you, a mushroom will spring out and you'll get a shock. But then you'll see that it's going to the right so you'll think: "I'm safe! Something strange appeared but I'm okay!" But of course when it goes against a pipe up ahead, the mushroom will come back! (laughs)

Miyamoto Right! (laughs)

Iwata At that point, even if you panic and try to jump out of the way, you'll hit the block above you. Then just at the instant where you accept that you're done for, Mario will suddenly shake and grow bigger! You might not really know what's just happened, but at the very least, you'll realize that you haven't lost the turn.

Miyamoto But you'll wonder why Mario suddenly got larger.

Iwata You'll try jumping and see that you can jump to higher places and smash through the ceiling, so it'll be clear that you've become more powerful.

Miyamoto It's at that moment that you first realize that the mushroom is a good item.

Miyamoto Of course it's because we wanted the player to realize that this item was different from a Goomba.

Iwata When I first realized that this had all been designed with that purpose in mind, I was really taken aback. When you tell people who weren't aware of it that the start of Super Mario Bros. was designed with this intention, it's rare that they won't be impressed.

Miyamoto Is that right?

Iwata It's not as if it was me who came up with it, but I've gone around bragging about it to plenty of people! (laughs)

Miyamoto (laughs) It wasn't an idea that was in the original design plan for the game. It's something we thought about as we were making the game. But happily, it turned out for the best…

Iwata So it's not the case that you can foresee everything before you start. Rather, as you develop the game, you gradually work on things by saying: "Perhaps it would be better like that… Maybe it would work better like this…"
