Use Case

Have you ever tried to develop a new gaming idea that isn't available in the market already? If you are a Game Designer or Developer, you will agree that it can be a daunting task. Wouldn't it be great if, instead, you could flip through tons of ideas, and pick the ones that sounded most interesting? This tutorial will show how you can build such an application. We will also show you how to share this with friends so that they can generate game ideas too!

In this tutorial, we will use OpenAI's GPT-3 to create a game concept generator, highlighting the capabilities of large language models. In addition, we aim to inspire you to take these ideas further, and develop your own creative models.

Prompt Creation

When you are ready to create your prompt, click AI Manager > Prompts > Add New Prompt, and fill out the following:

  • Name of Prompt: Video Game Concept Generator
  • Description: OpenAI Completion

Tags and Intelets can be left blank.

For deploying your prompt publicly at the end of this tutorial, you can add a default security policy configured by Mantium. Click Add Security Policies under Security Policies and drag Default Policies from All Policies to Selected Policies. Click Done to save - you will know the policy has been applied when its name is visible under Security Policies.

Prompt Body

For this tutorial, the prompt body is a collection of actual video game titles and descriptions. We have prepared a text snippet for you to paste into the prompt line.

Title: New World

Genre: MMORPG, PvP, Massive Multiplayer, Adventure

Description: Explore a thrilling, open-world MMO filled with danger and opportunity where you'll forge a new destiny for yourself as an adventurer shipwrecked on the supernatural island of Aeternum.

Then, select an engine.

  • Choose an Engine: Davinci

We selected the Davinci engine, which is the most powerful of OpenAI's available models. It provides great results for creative content generation. It is possible to select a lighter-weight engine as well, although results may vary.

OpenAI’s Engine Documentation

The prompt body itself is a collection of real video game titles, genres, descriptions and Metacritic scores. This serves as the "pattern" for the model to follow when generating new text.

Each entry in the prompt body includes the following:

  • Title - Game title
  • Genre - A tag that identifies the game type
  • Description - A description of the game's concept and gameplay
  • Metacritic score - Metacritic is a video game review aggregator site for rating the game out of 10.

Prompt Settings

  • Response Length: 200
  • Temperature: .9
  • Top P: 1
  • Presence Penalty: 0
  • Frequency Penalty: 0
  • Stop Sequences: ### ###

Response Length controls the length of an output response. The longer the response is permitted to be, the higher the potential is for it to become nonsensical. Since this is a creative completion prompt, nonsensical content is more acceptable and even encouraged.

Temperature controls “creativity” - higher temperatures will produce more unique and creative outputs but also are more likely to become nonsensical. A lower temperature is advised for a prompt that requires a well-defined response, as the model will choose words with a higher probability of occurrence. However, for creative and interesting responses, a higher temperature value is suitable.

Top P is another way to control "creativity" using a different probability method. It is recommended to use either Top P or Temperature but not both. The default value is 1.

Stop sequences are another method of controlling output - they allow you to define any text sequences that force the model to stop. If you don't have a stop sequence, the model might generate a stream of the requested response length or it may stop in the middle of a sentence.
Using "### ###" provides delineation that is clearly visible and not often present in natural language.

Test Prompt Text

Because these models are stochastic in nature, the resulting output will vary even when using the same input, but we have included a text snippet to run as a test:

Cooking with Confidence

We suggest running Test Run a few times to see the different possibilities of output, or think of your own unique video game titles to see what this model can create!

Once you are satisfied with the results, click Save.

Results & Conclusion

The model's output tends to result in funnier and more creative responses when given generic titles, such as "Sports Game 2022" as opposed to specific titles like "Zombie Invasion."

Below are a few examples of interesting results we have received in the past:
