Usually when most people make mock schedules, they put in new shows based on how much they like the premise. But in this game, you have to place yourself in the shoes of an Executive and imagine how they would handle scheduling and pickups.
For example, preferably I would like the CW to pick up these shows:
Riverdale
Untitled Mars project
Transylvania
But the CW would probably do something like this:
Riverdale
Frequency
No Tomorrow
Using my example, try making a list or schedule fitting of a network exec down in the comments below. Good luck, and feel free to make dumb choices. Execs make them around half the time.
