I'm sure there are other examples and I'd want to compare those first. I don't know whether those are using numbers like that or not. But if so, then the "word" they are supposed to represent should be in the alt name.
Not that we need to be concerned with game content for the purposes of our entries, but an LP of the game indicates D1AL-ogue is a named location within the game, named in the opening cut-scene.
