You _can_ write a game without any scripting language support whatsoever. You could also write the whole game in assembly if you so desired.

However, if every single time you want to change any piece of logic in your game, you have to do the edit/compile cycle, your development will be extremely slow. Especially if you compare with the ability to change code while the game is running.

Not having all the game logic in C or what have you makes the game easier to mod too.

1. I'm working on a game in Unity right now that takes about 10 seconds to compile and reload the assemblies for the scripting language (only about 2 seconds of that is actual compilation, the rest is time that would be applicable to an interpreted scripting language).

2. I've built games in C where the entire project took 4 seconds to compile. Incremental compilation and modular architecture can get that down to near instantaneous for most changes.

Take a look at handmade hero for an example of an architecture that allows you to hot-reload C code while the game is running.

That's completely architecturally dependent. You can make a game easy to mod for non programmers by storing data in a human readable/editable format. If you want to make it easy for players to write code there's a lot more work that needs to be done than just using a scripting language. For most games worrying about allowing modders to easily edit code is premature optimization.

I was involved in a game project that died extremely quickly a few years ago. The project lead made every decision re: architecture, tooling, etc. somehow involve worrying about modding. As a result, we ended up with nothing to show since everything got derailed by a bizarre obsession by one person with modding before we even had anything to mod. I believe that person doesn't take lead roles on projects any longer...

Fast iteration can be achieved with compiled game logic as well, it all comes down to how things are factored in your project.

An excellent example most with OpenGL experience may be familiar with is supporting hot reloading of GLSL for fast vfx development iteration. It's a compiled language, it gets compiled at runtime without significant delay, and most of us making games have created simple tools to support live editing of GLSL, maybe even supporting it in-game for dev builds.

The demoscene has even turned it into a form of competitive performance art:

Edit:

Forgot to mention Casey also goes through support of hot-reloading game logic using C in the Handmade Hero series on YouTube.

You could just expose the logic as DLLs though
