This is a collaborative world developer, the front end for our game’s planning process.
Here we can see the entire distribution of terrain to make sure everything makes sense.
By clicking any tile it takes us to another page with a variety of options; we can open the corresponding map in the map maker, change the terrain type and tileset, mark the map to be procedurally generated at playtime (which is the default) or to asynchronously append a note for all other developers to read.
