well it is a good idea elza, but it's very hard to develop with no real need I'm afraid. Instead, make your own
city layout with a
paper, pen and
ruler! I did that with a paper with squares, each square on the paper being one little block on the ground and wrote down the formats of buildings I need. Then I used ruler to set rows and columns for 2x2, 3x3, 2x4 building etc.
Also, I used the idea to connect all the buildings with Town hall with ONLY ONE path too! a path that leads from Town Hall all around the city and my layout was fascinating!
Sad to see there are no new posts on this subject, since all of those are proven to be helpful
Here is a little tip for new players and early ages, about
gaining blueprints: before you send someone an invite to be friends,
visit and make sure they have GBs of the blueprints you're looking for. If there are too many GBs and you still haven't made a single one, hold on and don't rush with filling the friends pool, since you need the friends who have maybe up to 3 finished GB's and as many as possible GB you need bp of.
The reason for that is when you hit the aid button, it is much more likely you will get a bp from the GB they already have, so you wont end up with 10 different GB, all of which have hardly 2 blueprints like I did. The other world I started played recently seem to prove this, because I got blueprints for the Tower of Babel, and that is exactly what I needed. So please correct me if got it wrong, since I'm pretty new myself, but I can see the difference between those two worlds I play in terms of GBs and their BPs income
