Collectible, Constructable, Digital Architecture.
The Classics are buildings you'd find in cities across the world like New York, Atlanta, Chicago, and San Francisco. They're hidden throughout the machine and in limited quantities.
Each Special Edition Golden building is a 1 of 1 limited edition BlockCities collectible and will never be reproduced. You can score one of these by being one of the first 50, 100, 250, or 500 builders.
