Naughty Dog was a great example of how productive Scheme can be in the hands of a few expert programmers. Founders attended MIT and CMU.

GOAL and GOOL were used in Jak and Dexter, Crash Bandicoot, and apparently brought back in The Last of Us:

In this 2014 GDC session, Naughty Dog's Anthony Newman shares an overview of the design and implementation of the melee system for The Last of Us.

Here is a project started in 2020 to reverse engineer the runtime and language which has playable games now:

The OpenGOAL project is a project to reverse engineer the Jak and Daxter video games and the custom programming language they were developed in: GOAL.

The long-term objective of the project is to make Jak and Daxter run natively on a PC by decompiling and recompiling it with OpenGOAL, our reverse engineered version of GOAL for x86-64 PCs. We do not host any game assets or copyrighted material from the game – we only host tools for reverse engineering and porting the game. The user must provide a copy of the game to use our tools.
