Docile NPCsDescription

Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)

Note that the hack is incomplete but feel free to enjoy the hack as-is.

0. DESCRIPTION

This is a quality-of-life mod for FF3/6 SNES which makes wandering NPCs more
readily yield ground to the player character.

In the original game, wandering NPCs have a tendency to be ever so slightly a
pain in the neck to get around. Most noticeably, if the player tries to move
into a tile that an NPC is exiting, the player may be out of luck if the NPC
decides to move back into the same spot.

Now, whenever the player character and an NPC are simultaneously attempting to
move into the same empty field map tile, the player character is given priority,
and the NPC's move is canceled.

This should make navigating though crowded spaces a bit less of a struggle.
