Hold my beer.

I'm gonna go tell the building manager that people would like our app better and we can save on platform costs by hiring one Unity developer.

That was not what I tried to say. Brogue, like other similar games, can be played in a TUI mode, in the terminal, or with a GUI. Same game, just different UI implementations, and both tend to be about equally laggy, or usually the GUI version is probably less laggy, since you can just blit glyphs without the overhead of terminal escape codes etc to draw the same symbols in the TUI. And Brogue just uses SDL, not a game engine, so that is not relevant at all.

But your snarky reply is probably also wrong anyway, since I would be surprised if there is no business software made using game engines. Tesla is known to have used (but not anymore?) Godot for making GUIs for their in-car displays for instance. I have bought applications (not games) made using both Godot and Unity. Not saying it would be a great idea, in general, to use those engines for business applications, but people are not known for always using the best possible tools, are they, and it certainly would work in theory?

Not very familiar with Unity, but Godot has very nice GUI widgets. Same style of WYSIWYG editor like old Visual Basic or Delphi really. You drag widgets to place them on the screen, set properties, add scripts to react to different events. The entire Godot IDE itself, a very non-trivial application, is implemented using Godot's own GUI framework.
