Advanced Short Sim/Branching Story Technique:A Helpful Host
In this sim, presenting an introduction to Econ 101 supply, the player has to assemble food trucks and other options to feed a growing crowd of people.
In this case, the on-screen character is positioned as a helper and collaborator (and conduit to the outside world), not as an authority figure or a judge. The voice I had for him was Iron Man's Jarvis.
Further, the player could create different solutions to the problem, such as here to feed 100 people, not just find the one
Feedback can be still be given in a Jarvis kind of way (and yes, the player's "voice" is Tony Stark)...
...and artifacts can be created "as a courtesy" to the player.
