State of The Sim – Year 3 Month 3

I’m excited to share the following update on the state of Meco Rocket Simulator.
As always, I have remained firm in crafting a high-quality product. The side-effect is increased delivery time. That said, I am confident you will appreciate the result.
A major decision was made to migrate Meco from my custom game engine to Electron and Babylon.JS to ensure that development can be focused on the simulation kernel’s features rather than the game engine’s features.
As a result, I am pleased to note that the UI code is in a good position to be open-sourced for modification and add-on development by anyone that picks up React and TypeScript. Though this is a great first step, there’s still some work before it can be an easily moddable game.
Stay cryo-cool,
