JL made the original project and I thought it'd be fun to expand on the concept a little and show different player characters aside from our boy Mac. You'd get this screen either at the start of story mode or before a custom night to choose who to play as. Aside from possible difficulty changes in story mode, there'd be no gameplay differences between the crew. Also yes this was inspired by Frickbear's 3.
since everyone's doing this now, I guess I will too.
