I wouldn't say it works well for games. The "no-code" solutions like blueprints or shader graph are more of a visual configuration for technical artists to use, but built on pretty well defined code-heavy systems. You might use a visual system to configure something like a AI Behavior Tree, but you wouldn't be able to build a whole new type of system with it.

That said, they are very good and powerful, and open up a lot of flexibility to tech artists.
