So i want to make a roleplay that takes place mainly in nature
and depending on how much players travel and migrate I want to figure out
how to operate travel when they might wish to stay separate from each other.

Would a grid system be good or simple map be better. I want to have spatial mechanics
that arent too complex or matter when they are in the same areas, but I do want there
to be sometimes down time where travel has to happen to reach each other. I want there 
to be the option to avoid other players and get lost.

Any tips and suggests. I for now want to focus one if treks happen via walking as I don't plan
on having any vehicles.
