I still don't understand why some printed lines - so not a game feature but something "outside" of said tiles - should be considered to make a rule.
The printed line where the device used by HiG to separate a multi-tiled tableau into independent tiles.
This was used in the Wheel of Fortune and the city of Carcassonne when used tableaus for it instead of the original individual tiles.
Original 3x4-tile configuration for the city of Carcassonne in C1 sold as 12 tiles, which had to be assembled (front and back):
In 2015, HiG released a version of this setup as a 3x4 tile tableau, with one additional city segment at the top not included in the original design. The limit of the original tiles outside the city where marked with white lines.
The outer area of the city of Cacassonne can be occupied by meeples, the fairy and the dragon... The interior part of the city of Carcassonne is out of limits for the fairy and the dragon.
A similar approach was used in C2 for easy setup plus a two-sided version of the image: two 2x3 tableaus with flags marking the districts and without them.
The two 2x3 tableaus could fit in a major expansion box. This could not happen with a 3x4 tableau.
The Wheel of Fortune features a 4x4 tile tableau. The outer part is also divided by white lines to separate tiles. The same approach was used to separate tiles without provided 16 actual tiles for it. Since the setup would be somewhat cumbesome.
So if I get a custom 3x4 tableau without printed lines, it won't allow the dragon to enter if the fairy is present on any tile?
That would be the idea. No big deal.
You said "Each one of those tiles is independent", referring to the 3x4 tableau. Why aren't the 4 tiles in the 2x2 Expansion 11 independent? Just because they didn't draw a line?
This is chaotic
When required
My problem here is that there seems to miss a requirement. It's... random?
The lines separating tiles make the difference. No lines means that all the square spaces conform one single tile.
