The importance of Game Prototyping

  • Finnish game developer and a cofounder of the game studio Nolla Games. He is known for his games “Noita”, “Crayon Physics Deluxe”

  • Tango Gameworks Game Director for the critically acclaimed, rhythm action game, Hi-Fi RUSH. Prior to working on Hi-Fi RUSH, Johanas directed The Evil Within 2 in 2017.

Game Design: Prototypes

About the Lectures

This reflection is based on two distinct lectures about prototyping in game design. The first lecture is by Nolla Games’ co-founder, Petri Purho who shared his iterative idea of prototyping games following this process to shape the rest of the game elements. In contrast, the second is a video interview with John Johanas, the game director of Hi-Fi Rush. He presents prototyping as a way to reach a very clear idea and his process focuses on getting “that one thing that makes the game unique” right.

On the one hand, Petri Purho’s lecture focused on the importance of a rapid prototyping phase where you focus on getting the game mechanics and systems working and then exploring the shape of the game by iterating. On the other hand, John Johanas started this process with a particular idea in mind. All his iteration process was about reaching the destination using a ‘jigsaw puzzle’ approach, which means to start building parts of the project knowing more or less that they will fit somewhere. Both lectures had in common that they highlighted the importance of keeping the prototypes very simple and with as less team members as possible involved even though those two games have really different scopes and budgets.

This way of prototyping resonated with my own method since I believe that it is of crucial importance to keep very simple elements when creating prototypes. However, it is tricky to do it when you are prototyping visual aspects, because there is an inner drive to make things look perfect and separating from that needs extra effort from the artist’s side. In particular, I find Johanas’ way more aligned with my own thinking process. His ‘jigsaw puzzle’ concept resonated with the way I approach the creative process.

Hi-Fi Rush - Prototype VS Final Game

Regarding my own work, the first lecture gave some insight when prototyping the Game Project I pitch. I tried to keep the “rapid as a state of mind” approach proposed by Purho and that made me iterate ideas faster. I was amazed by the complexity of both lectures’ projects, in particular, Hi-Fi Rush’s goal of creating an action rhythm game where everything moves to the beat seems insanely difficult, but witnessing how they managed to polish their prototypes was inspiring. They managed to simplify a complex problem with outstanding game design. Additionally, the fact that the early prototypes of Hi-Fi Rush impacted the final game in aspects like narrative, UI and environment design was surprising and it is an unexpected benefit to focus on prototyping first.

The advice given by Petri Purho on creating bad games to spark ideas was refreshing, and it took some pressure off our shoulders for the next projects. Seeing all of his prototypes come together into a successful commercial game was a unique experience and I would like to emphasize the importance of keeping a record of your own process when sharing your knowledge.

Finally, I would say that my perspective on game design has evolved after the lectures. Not only have I found new ways of testing key ideas on my future games, but also have released the pressure from my shoulders when testing ideas. In future projects, I want to try to keep the visual aspect minimal during prototypes, unless the key element of the game is the art. In this case, all the efforts will be focused on getting that crucial element right.
