Traditional 2D Prototype

My second adventure game prototype is a traditional 2D adventure engine designed to explore whether the following are feasible:

  • Developing it as a CocoaPod for reuse over a number of games
  • Using a standard JSON format that would describe room parameters (e.g. walkable areas, object locations, NPC locations, environmental triggers, etc.)
  • Using a separate JSON format to describe dialogue trees, with support for triggers, branching dialogue, and basic conditionals
  • Recreating something like this in C# for use in Unity

Talking Head Animation Frames

I’m developing a dialogue editor for adventure games and I want to have a screen where I test out the dialogue: see how it flows, test user interaction, that sort of thing. I thought it would be fun if to have actual animated characters speaking the dialogue.

AR Prototype

My first adventure game prototype is an ARKit-based app designed to explore the following:

  • ARKit plane detection and the automatic insertion of models once suitable planes have been detected (as opposed to user-initiated placement)
  • 3D modelling workflows between Blender and Xcode
  • Map searches for generic locations and then, using the results, managing distance, accessibility, storage, and game state
  • Geofencing triggers and how they might progress the game

Prototype Plans

I am in the process of building two prototypes to explore different ways I could build an adventure game on iOS.

The first is an ARKit app. You interact with characters and then they send you off to real world locations to meet other characters, collect items, and solve puzzles.

The second is a more traditional 2D engine using SpriteKit and is heavily inspired by LucasArts’ legendary SCUMM engine. I want to create something modular that could then be used for many years in dozens of games.

Adventure Game Numbers

Steam Spy is a service that reports the number of owners of games on Steam using their API and a little modelling/guesswork.

Entrepreneur Math is when you make up numbers based on unrelated or partial data to prove to yourself how successful you’re going to be. For example: “There are 80,000 searches a month for ‘Cats Wearing Heels’. If my website,, gets 10% of those searches, then that’s 8,000 visitors a month. If 1% of those then go on to buy two pairs of my designer cat heels, then I can easily make $4,000 a month”.

The State of Adventure Games

When it comes to adventure games, I have been focusing on the past, working my way up to the present day. Up until this point, I have been a player only and therefore haven’t really been paying attention to the current state of things.

As 2018 rolled around and I finally committed to creating my own game, I realised that I had no idea what the current market for adventure games was actually like.
