Fantastic Worlds Advance Slot Properties

An authoritative guide to the unique characteristics of the 'advances slots' that intertwine to make the Civ2 technology tree.

Version 1.4.

by William Keenan

The Advance Slots

Creating an engaging scenario or mod-pack for Civ2 will in all likelihood involve modifying the advances or technology tree as set out in scenario's rules.txt file. The tree itself can be modified, however a large number of 'slots' (row position in the table) have unique characteristics and care must be taken to ensure that tribes begin with and if appropriate discover technologies appropriate to their circumstance.

Version Changes

Version 1.1 clarifies several differences between FW scenarios and ToT scenarios where known. ToT research in no where near complete so there may be several omissions.

Version 1.2 corrects a long standing misconception about the effects of technology on temples. The effects of advances on the literacy demographic have been revised. ToT advance properties have been removed from this guide and now have their own guide.

Version 1.3 clarifies the properties of Democracy, Explosives, Fundamentalism, Nuclear Fission, Magnetism, Radio and Refrigeration.

Version 1.4 identifies the special unit obsolescence rule associated with Gunpowder and lists the affects of that Flight, Invention, Navigation, and Rail Road have on the gold and science payoffs that caravan deliveries produce.

How to Use this Chart

Slot is the order in which the technologies are listed in the rules.txt. The events.txt file sometimes refers to technologies by slot number.

Code is the abbreviation used to refer to the technology slot in the rules.txt file.

Trigger Effects of Discovery are all hard coded in the software and unchangeable by scenario designers. Effects that are event driven, like winning the game by discovering Transcendence, have been purposely excluded from this chart.

References to other parts of the rules.txt file (improvements, trade items, units) and support files (cities.gif, people.gif) always refer to the appropriate slot in the given section not necessarily the named item. For example if your renamed temples to cathedrals and cathedrals to museums then the discovery of theology would make museums more effective rather than cathedrals.

Technologies Table

Slot	Code	Advance	Trigger Effects of Discovery

2	Amp	Amphibious Warfare
3	Ast	Astronomy
4	Ato	Atomic Theory
5	Aut	Automobile	Increases population based pollution. Automobile works with Electronics to change city pictures to the modern style (6th row in the cities.bmp file). Automobile works with Electronics to change the look of people to the modern style (4th row in the people.bmp file).
6	Ban	Banking
7	Bri	Bridge Building	Allows settlers units to construct roads (and railroads) in river squares.
8	Bro	Bronze Working
9	Cer	Ceremonial Burial	Ceremonial Burial allows temples to make one additional person content. See also Mysticism.
10	Che	Chemistry

12	CoL	Code of Laws
13	CA	Combined Arms
14	Cmb	Combustion
15	Cmn	Communism	Allows the government type of the same name. The discovery of Communism reduces the effect of Cathedrals by one. Cities produce more partisans.

18	Cst	Construction	Construction allows settler units to build Fortresses.
19	Cor	Corporation
20	Cur	Currency
21	Dem	Democracy	Allows the government type of the same name. Courthouses make one content citizen happy if the nation is operating under Democracy. However, the Democracy advance is not required for this effect to take place.
22	Eco	Economics
23	E1	Electricity
24	E2	Electronics	After the discovery of Electronics an additional citizen in each city is made content by coliseums. Electronics works with Automobile to change city pictures to the modern style (6th row in the cities.bmp file). Electronics works with Automobile to change the look of people to the modern style (4th row in the people.bmp file).
25	Eng	Engineering
26	Env	Environmentalism	Decreases population based pollution.
27	Esp	Espionage
28	Exp	Explosives	Contrary to popular belief, Explosives does NOT inherently allow transformation orders or display the "New Order: Transform" message. The ability to transform is inherent to unit in the Engineer slot of the RULES.TXT file. When this unit first becomes available the message will be displayed.
29	Feu	Feudalism
30	Fli	Flight	Reduces by one third the amount of gold and science produced by caravan delivery. This affect is cumulative with all other modifiers.
31	Fun	Fundamentalism	Allows the government type of the same name. The Fundamentalism advance does NOT inherently allow Fanatics to be build. Only nations operating under the Fundamentalism government can build the Fanatics unit once the advance making the Fanatics available has been discovered. Upon changing government type from Fundamentalism to any other type all cities producing Fanatics will switch to producing the unit in the Riflemen slot whether or not the nation has the prerequisite advance to build this unit.
32	FP	Fusion Power	Eliminates the threat of Nuclear Power Plant meltdown. Adds 25% to spaceship mass/thrust paradigm.
33	Gen	Genetic Engineering
34	Gue	Guerrilla Warfare	Captured cities produce partisan defenders. Changes the types of Barbarians units produced by Goody Huts. Changes the types of land-based random Barbarians units produced.
35	Gun	Gunpowder	Sells all Barracks when discovered. Increases Barracks maintenance cost by one (cumulative with Mobile Warfare). Changes the types of Barbarians produced by Goody Huts. Changes the types of land-based random Barbarians units produced.
36	Hor	Horseback Riding
37	Ind	Industrialization	Changes city picture to industrial (5th row in cities.bmp) in any non-fantasy game. Changes the look of people to industrial (3th row in people.bmp). Changes the types of land-based random Barbarians units produced. Increases population based pollution. Upon discovery the Industrialization advance oil appears as a supplied trade commodity in most cities.
38	Inv	Invention	Reduces by 50% the amount of gold and science produced by caravan delivery. This modifier is NOT cumulative with Navigation or the Turn 200 effect, but is cumulative with the reductions of Railroad and Flight. Free advances can no longer be gained from goody huts. Invention works with Philosophy to change the citizen look to the renaissance style (2nd row in the people.bmp file).
39	Iro	Iron Working	Changes the types of Barbarians produced by Goody Huts. Changes the types of sea-based random Barbarians units produced.
40	Lab	Labor Union
41	Las	Laser

45	Mag	Magnetism	Changes the vessel type of sea-based random Barbarians.
46	Map	Map Making	Allows civilizations to exchange maps.
47	Mas	Masonry
48	MP	Mass Production	Increases population based pollution.

54	Mon	Monarchy	Allows the government type of the same name.
55	MT	Monotheism	Monotheism allows Cathedrals to make three people content. Note that Cathedrals do not function without the discovery of Monotheism or Theology and Mysticism. Changes the types of Barbarians produced by Goody Huts.
56	Mys	Mysticism	Mysticism allows temples to make one additional person content. See also Ceremonial Burial.
57	Nav	Navigation	Reduces by 50% the amount of gold and science produced by caravan delivery. This modifier is NOT cumulative with Invention or the Turn 200 effect, but is cumulative with the reductions of Railroad and Flight. Navigation reduces the chances of triremes floundering. Changes the vessel type of sea-based random Barbarians.
58	NF	Nuclear Fission	Upon discovery the Nuclear Fission advance uranium appears as a demanded trade commodity in most cities. Uranium begins appearing as a supplied trade commodity in new founded cities.
59	NP	Nuclear Power	Nuclear Power increases the movement allowance of ships by one.
60	Phi	Philosophy	The civilization that first discovers Philosophy gains a free advance. Invention works with Philosophy to change the look of people to the Renaissance style (2nd row in the people.bmp file).

68	Rec	Recycling
69	Ref	Refining
70	Rfg	Refrigeration	Allows settlers and engineers to double-irrigate lands. All city squares are automatically upgraded to farmland (double-irrigation) when Refrigeration is discovered. The benefits of double-irrigation, 50% food production bonus, will only be realized once the city has built the Supermarket improvement. Interestingly, the Refrigeration advance is not needed for this to take effect.
71	Rep	Republic	Allows the government type of the same name.
72	Rob	Robotics
73	Roc	Rocketry
74	San	Sanitation	Decreases population based pollution.
