One of the key functions of Architecture is that the amount you put into it invariably determines what you get out of it, and the more thought and effort you put into organization, the less work you'll have to do on your own. There are always more ways to streamline the process of completing a test, whether it's trying to influence a pass in Towers, creating an Obelisk queue, or getting all 49 people to actually help with a Megalopolis. This is somewhat in the spirit of the lattermost; the first Architecture test I devised, there are multiple ways to pass it by intent.
It's also something of a 'straight' test, with much less competition than others. Wonder if there's a way to change that... --Sedelyan
Thankfully, there are always ways to do so. Take, for example, a carousel: a tower of life and death, with predators and prey rotating in a circle of grand harmony. An architect who can build one of these has their work cut out for them, but it can certainly be its own reward!
A Carousel Tower is initially built in a construction site, and requires a very large number of materials -- aside from the standard bricks and boards, there's also a small amount of marble, and at least one three-output gearbox. This means that the lead architect will, initially, have to deal with accumulation, and may attempt to find help from the others working on it. When the Tower has been built, twenty-one slots are placed on the building itself, each corresponding to a single animal and a tier.
The Carousel has three tiers, each with seven fantastic animals: the Ram, the Phoenix, the Cat, the Jackal, the Serpent, the Bullfrog, and the Hippo. Each has its place in mythos, and so each has a place on the carousel. The animals themselves are decorated with a number of random materials, to be explained later.
Once the Tower's form has been built, the slots may be filled. Each player, with the exception of the architect, may take one and only one slot; therefore, up to 21 other players are necessary to fill a Tower. Once a player has taken a slot, they may change it; the architect of the tower may take as many slots as he or she chooses.
The materials and quantities required for any player to build within a Tower's slot are semi-random; while some material requirements may overlap, others will be completely different in specifics...and the quantities will be different for each player, similar to megalopolis sites. They include a two-output gearbox, a number of treated boards, marble, and cut gems. A player may abandon their slot and choose another unoccupied one; therefore, they may make a list of all twenty-one slots available to them, and the materials required for each. It is the job of the Tower's organizer to give each player a slot that they will use most efficiently; this usually falls to the creator of the base. As said base creator may take as many slots as he or she chooses, it may be more efficient in the long run for them to take those!
Ultimately, when all twenty-one slots are filled and built, the owner of the Tower passes; a beacon shines at the top of the building, and the three tiers begin to rotate. Other builders are credited with one of the seven animals, whichever they built; any who have completed all seven subsequently pass.
