Launch Arco Trick
The Launch arco trick can be done in the DOS & Mac v1.1 and also Window version of SimCity 2000. After building 301 launch arcos & after the year 2051, a message will appear saying: "The exodus has begun" and the arcos will appear to explode one by one (a process which takes over two minutes to complete) and the game will show another message: "Your launch arcos have departed into space to find new worlds. You have been compensated for the construction."

- Simcity 2000 (PC) - Exodus Event - full playthrough (35min HD)
SimCity 3000 originally planned to feature arcologies but they were cut at some point in development. The only confirmed traces of their existence is an unused audio file found in the sounds folder and two pieces of concept art for the Plymouth and Darco arcologies.
Based off what little information there is, they likely would have been very similar to their SimCity 2000 counterparts based on footprint and capacity but the effects on the cities they are built in would have had much wider range considering SimCity 3000's more advanced simulation.
Arcologies were likely cut in favor of dense 4x4 zoned buildings and more specialized reward buildings like the Spaceport.
SimCity Creator (DS)
In SimCity Creator for Nintendo 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 work 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 Arcology returns as a landmark in the SimCity: Cities of Tomorrow expansion. It is available by pre-ordering the expansion. The building is placed under the Tourism tab of the City Specializations. Upon plopping down the structure in one's city, tourists and prisoners will begin settling into the edifice. After 5,000 spots are filled, the player is given the option to launch the Arcology into deep space. Upon launch, the player would be rewarded a large sum of cash from the 'ticket sales' of the landmark.
