Currently the NPC commands need to be typed exactly as coded or they won't work.
For example,
follow me (without a period)
stop following
etc.
Unless they are coded that way for optimized code execution purposes, it would be an RP enhancement if the NPCs could do a string search. Or whatever the MOO equivalent is.
Such that, we can type
"Hey bata. I need you to follow me."
or
"I'm good now. You can, stop following."
This would align with the staff encouragement to flesh out our conversations with NPCs, instead of typing the bare minimum to make the underlying code work.
