I am spending my retirement working part-time on a realistic spacecraft simulator (3D, VR) set in the late 20th century on a fictional moon made of Tungsten ("Tungsten Moon"). For some reason, I decided the spacecraft needs a "real" flight computer with code that can be modified by the player, so I am now deeply immersed in coding a Forth virtual computer ("AMC Forth") to run in-game. It will control the navigation and systems on the spacecraft. If you've gotten this far, and you're intrigued, you can try the free demo on Steam (no Forth machine yet).
