Ahoy, Mateys! Building a Western Pirate Game with AI-Powered Dialogue

How Amazon Q and Other AWS Technologies reduced the development cycle and enabled an immersive Western Pirate RPG game to come to life!

Published Jan 14, 2025
Ever dreamt of sailing the high plains, six-shooter in hand, trading witty banter with scurvy landlubbers? We have! And that dream has become a reality with our new Western-themed pirate game, built in Unreal Engine and powered by cutting-edge AI. In this blog post, we’ll share the development journey, focusing on how we leveraged Amazon Web Services (AWS) and Amazon Q to create a truly immersive and dynamic world.
Our biggest challenge was creating believable and engaging dialogue for our Non-Player Characters (NPCs). We wanted each encounter to feel unique and reactive, avoiding repetitive and predictable interactions. The solution? Large Language Models (LLMs).
Harnessing the Power of LLMs with Amazon Bedrock
We chose Amazon Bedrock as our gateway to powerful LLMs. Bedrock provides access to a variety of foundation models, allowing us to experiment and find the perfect fit for our game’s tone and style. By integrating Bedrock into our AWS infrastructure, we could seamlessly connect our game to these models for real-time dialogue generation. This means every conversation in our game is dynamically generated, ensuring a fresh and exciting experience for every player.
Conquering Infrastructure and Game Development with Amazon Q
Setting up and managing the necessary AWS infrastructure for this project was a daunting task. We needed to handle everything from compute instances for running the game servers and LLM interactions to setting up proper roles, permissions, and security measures. But the challenges didn't stop at infrastructure. Integrating the LLM dialogue into our Unreal Engine project also presented its own set of development hurdles. This is where Amazon Q truly became our first mate.
Amazon Q, with its ability to generate and autofill code, proved invaluable in streamlining our entire development process, from infrastructure to in-game integration. It significantly reduced the time spent on tedious tasks, allowing us to focus on what truly mattered: refining the LLM integration and optimizing dialogue generation performance.
Listed below is a diagram of our infrastructure setup for the LLM generation. This was inspired by this AWS blog post.

AWS Infrastructure - NPC Dialog
To bring our NPCs to life, we implemented a sophisticated dialogue system powered by AWS. When the player initiates a conversation, an API Gateway endpoint receives the request, triggering a Lambda function. This function gathers crucial information: the current game context (location, time of day, active quests, etc.) and the player's dialogue. To enrich the conversation, we leverage DynamoDB. First, we retrieve the specific NPC's profile, including personality traits and backstories. Second, we access the conversation history between the player and that NPC, ensuring continuity and creating a more immersive experience. This combined data forms a detailed prompt, which is then sent to Amazon Bedrock. The LLM's response isn't just plain text; we parse it to identify any changes to the game state. This allows for dynamic quest progression, such as opening new quests, closing completed ones, or updating existing objectives based on the conversation. Finally, the generated dialogue is processed to reflect a pirate-themed dialect, further immersing the player in our Western pirate world.
Specifically, Amazon Q helped us:
  • Automate Code Generation (AWS & Unreal): Q helped us quickly generate code for interacting with AWS services, including Bedrock, and assisted with writing C++ code for our Unreal Engine project. This drastically reduced development time across the board.
  • Configure Roles and Permissions: Setting up secure access to our AWS resources is crucial. Amazon Q simplified the creation of IAM roles and policies, ensuring only authorized services and users could access our infrastructure.
  • Provision AWS Infrastructure: Q assisted in configuring and deploying the necessary AWS resources, such as EC2 instances, Lambda functions, and API Gateways, saving us countless hours of manual configuration.
  • Accelerate Unreal Engine Development: Beyond infrastructure, Amazon Q provided valuable assistance within our Unreal Engine project itself. Its intelligent autocomplete feature significantly sped up the coding process, reducing typos and streamlining common tasks. Furthermore, Q provided suggestions for code improvements and quickly generated boilerplate code for repetitive tasks, such as setting up character animations or handling input events. This allowed us to quickly prototype and iterate on gameplay mechanics.
By automating these tedious tasks, Amazon Q allowed us to dedicate our efforts to:
  • Optimizing LLM Performance: We focused on fine-tuning prompts and parameters to ensure the LLM generates contextually relevant, engaging, and consistent dialogue.
  • Improving Dialogue Generation: We worked on integrating the generated dialogue seamlessly into the game, considering factors like character personalities, in-game context, and player actions.
  • Developing an Immersive Gaming Experience: The devil is in the details with game development. Ensuring assets are thematically on point, the island and map are interesting to explore and the cities and interactions are fun make a good game great. Because development time on smaller coding work could be largely automated we could focus on these details.
The Result: A Living, Breathing World
Thanks to the power of Amazon Bedrock and the efficiency brought by Amazon Q, we've created a Western pirate world that feels truly alive. Every encounter is unique, every conversation is dynamic, and every player has a truly personalized experience. The added benefit of Q's assistance within Unreal Engine itself has allowed us to develop and iterate on our game mechanics at an unprecedented pace.
We're incredibly excited to share our game with the world and let players experience the magic of AI-powered storytelling. Stay tuned for more updates, and keep an eye out for our upcoming release!
