Arcologies are futuristic self-contained cities where a huge population is all contained in one building. Arcologies are featured in SimCity 2000, SimCity Creator DS, & SimCity 2013.
Sim City 2000Edit
Sim City 2000 features 4 arcologies. They will be available once you reach a population of 120,000 and once you're in the year when they're invented.
- Plymouth Arco
- Forest Arco
- Launch Arco
Launch Arco TrickEdit
The Launch arco trick can be done in the Windows version of Sim City 2000.  After building 450 launch arcos, a message will appear saying: "The exodus has begun" and the arcos will explode and show another message: "Your launch arcos have departed into space to find new worlds. You have been compensated for the construction."
Arcos, along with the Braun Llama dome were originally going to be part of SC3K but were scrapped for unknown reasons.
Sim City Creator (DS)Edit
In Sim City Creator(DS), arcologies will appear in the post global warming age. They are similar to the ones in SimCity 2000.
Arcologies make a return in the form of a great works in the SimCity reboot. Like other great works, multiple cities in a region can work together to complete the structure. Once a city in the region reaches 58,000 residents the construction of the arcology is unlocked, the region then needs to collect a million simoleons, 2,800 tons of metal, 1,000 tons of alloy and 60,000 crates of televisions.
The upkeep is 300 simoleons per hour.
The Launch Arco will return as a landmark in the Cities of Tommorow Expansion.
