>I have yet to see a "Visual" programming environment that is even close to as efficient as normal programming.

There are more than just programmers on modern game projects. I imagine visual scripting is an enormous boon to teams because a designer or someone who makes rules isn't blocked on a programmer implementing those rules. The non-programmer can get the basics down in the visual scripting tool, then the programmer can finish it and tighten it up. I'd love a tool like this in web development that let PM/BAs get started writing test cases they could hand off to me, for example. (I'm aware that tools like this do exist, was trying to be illustrative)
