At the risk of Jabba spoilers I won't go into too many details, but there's one campaign mission that allows the rebels to perform a special action if they are adjacent to one of the tile walls. Which brought us to the question of what is considered adjacent to a wall, and whether a figure that is on a space next to a corner is considered adjacent. I'll see if I can't demonstrate with a grid here:

[X][X][X][O]

[X][X][O][O]

[X][O][R][O]

O = Empty Space, R = Rebel Figure, X = Nothing (empty tabletop space outside of the map tile)

One of us argued that the figure was next to a corner, not a wall, and was not actually adjacent to the wall. This person figured that a wall should work similarly to a door, which has the rule:

The spaces that share an edge with a door are the only spaces that are considered to be adjacent to that door.

The other argued that without any explicitly written rules, like the one above specifically written for doors, that adjacency should work just like it does for any other space, which is to say:

Quote

A space is adjacent to each other space that shares an edge or corner with the space.

To which the first person responded that the area outside of the tile isn't really a "space", and that we're not worried about being adjacent to that exterior "space" but rather to the wall itself (which lies on an edge).

I was one of those people, but I could actually see it going either way. More specifically I guess I can see how neither rule fully covers what it means to be adjacent to wall.

Anybody have any thoughts?

See also the core mission Incoming, which uses "adjacent to the outside edge of a map".

I think the adjacency rules won't help you much, because (like you found out) they only define adjacency to spaces or figures. You need to fall back to everyday interpretation of adjacent.

Thus, I would say if a space shares an edge or a corner with a wall, the space (and a figure occupying the space) is adjacent to the wall.

If you consider thematics, it would be strange to exclude the spaces that only share a corner.

(Edit: doors are very special objects, so you can't infer anything from the door rules.)

I'm about to play this mission, and I hadn't thought of that possible confusion yet. Thanks for pointing it out! I'm inclined to agree with a1bert on this; doors don't help much because they are bizarre, and everything else is adjacent even if only corners are touching.

Glad to hear that we played it correctly in the end, or at least that we went with what seems to be the common interpretation. I figured that it would make sense from a thematic perspective that if you could move there then you could also do the special action there. But as with any edge case (hah!) in a board game like this, the thematically appropriate ruling is not always the correct one.

I agree with both of you, though, that since we don't seem to have been given an explicit ruling in the books that it makes sense to play thematically. Thanks!

Also in the end I don't think it would have ended up affecting the mission outcome either way, though it was starting to look tight there for a second.
