I once had a goal to explore how the humble 8x8 tile could express so much with so few pixels:

  1. Looking At Pixels Part 1: Characters
  2. Looking At Pixels Part 2: Buildings in Gen 1 Pokémon Cities
  3. Looking At Pixels Part 3: Let's Look at Each Building Type in Gen 1 Pokémon

But as time moved on, it became much more Pokémon RBY based. So this post kicks off a more apt name for this series of posts, Let's Look at Pokémon Gen 1.

We're back at looking at cities and understanding how a player is confined to the rectangle limits of a city. We've looked in depth already at each city in Looking at Pixels Part 2 so we can almost think of this as an addendum to that post.

Note that come most cities will have a combination of any of the below to create their limits. I'll also be giving an idea of the amount that tile is used with low/medium/high indicators. Note: if the boundary tile is within the city but not used as a boundary itself, it is not counted in the city list.

Large Fence

A large cylinder

I'm not entirely sure what this is named, but often it's seen in a line on land and in water to close up a city. I almost see it like a concrete pylon or a large white floating tank when in the water. Great examples include Pallet Town, Cerulean City, Cycling Road, and Cinnabar Island.

Extensively used when water needs a boundary.

All cities with this boundary:

City Amount of this boundary
Pallet Town High
Viridian City Low
Pewter City Medium
Cerulean City High
Vermilion City High
Fuchsia City Low
Saffron City Medium
Cinnabar Island High

Small Fence

Two fence posts

Classic fence posts. Neat that they come in pairs.

All cities with this boundary:

City Amount of this boundary
Viridian City Low
Lavender Town Low
Vermilion City Low
Saffron City Low

Tree

A bushy tree

Dotted all over the place, the single tile tree is an easy way to add a natural wall. Celadon City is the only city to use exclusively use trees as a border with Fuschia City a close second.

All cities with this boundary:

City Amount of this boundary
Viridian City Medium
Pewter City Low
Cerulean City Low
Vermilion City Low
Fuchsia City High
Saffron City Low

Cliff/Mountain/Hill/Rock Wall

A tidy example of impassable hill

Whatever you want to call it, it's made of rock and it's impassable. Super common among the more northern and north eastern routes, it can also be seen in a a few cities too.

All cities with this boundary:

City Amount of this boundary
Viridian City Low
Pewter City Medium
Lavender Town High

Buildings

Buildings used as impassable walls here in the north east of Saffron City

Some cities throw in some dense building zones to wall off the player.

All cities with this boundary:

City Amount of this boundary
Vermilion City Low
Fuchsia City Low
Saffron City Low
Cinnabar Island Low

Sign

The humble sign in north east Vermilion City

A cute one I nearly missed and it's only found in Vermilion City and three times at that.

Vermilion City Low

Conclusion

RBY has only six ways to keep a player from getting out of bounds in a city - with fences, trees and rocks being by far the staple. A lot simpler than I originally thought.
