Ok so it has been discussed before but with no real solution to the problem of keys and teleporting.
If indeed teleporting is on the way out but the problem of keys / gates is holding it back.... here is a simple ( not being a programmer i can only hope the code is simple)
way of removing all teleportation.
1st : Gates. on unclaimed land anyone can open them just like fences.
on village claim only village members can open them
on personal claim ( supperseding village) only that person may open them ( or anyone with trespass permission )
- in any case the gate only stays open as long as you are within x(#) of tiles them auto closes
2nd : teleporting. simply gone. without keys walls will stay effective no need for CR's leading out. no HF or village jumping. with one small change here. add guiding arrows like while in party to keep people from getting lost or don't might be fun if people can't find their way back to their farm.
That's my 2 cents on getting rid of teleporting
PS: bridges would help in the creation of world spanning roads.
