It'll take me a few minutes to digest all that, but it looks really good.

Trade and StarBases
v1.01

Text from Manual. I recommend to read it first.
Trade
Once you have researched Trade, you gain the ability to build freighters. Freighters are a special unit that once built, can be sent to a foreign star system to create a trade route. Once this is done, a trade ship then travels between the source star system and foreign destination star system and back. The income you receive from trade comes as that trade ship moves each turn.

How much you receive from trade per month varies somewhat as the trade ship travels. The further along the route, the more the trade route brings in. For instance, a trade ship may only bring in 1 bc per turn when it first leaves. But on its way back, it may be bringing in 5 bc per turn.

This has an important implication: The longer the trade route, the more the trade route is worth. It also means you can create an effective economic blockade. In essence, you can cripple the economy of an enemy by keeping trade ships from being able to travel the whole route. If a particular civilization can’t keep their trade ships safe, outside their immediate territory then their economy will suffer.

The other factor in determining how much a trade route is worth is the combined wealth of source star system and destination star system. Generally speaking, it is best to have your freighters come from your best star system and go to the best star system in a particular player’s civilization.

Trade has a few side effects as well. First of all, both civilizations involved in the trade receive equal compensation from trade. So it’s probably best not to trade with civilizations you later expect to go to war with. Secondly, such trade influences diplomatic relations. Since war cuts off trade between the two warring factions, if your trade represents a sizeable percentage of their income, they are a lot less likely to want to go to war.

Star bases

3) Trade bonuses - when a mini-freighter flies through a sector that has a star base with trade upgrades, it can increase the amount of trade you receive from that trade route while the mini freighter is in that sector. So a trade empire might create a whole line of trade star bases that follow its trade routes.

// End of Manual

Then freighter creates a trade route, it immediately ‘teleports’ to a planet where it was built (note that it’s graphics changes). Then it starts to move between two planets. It’s speed = 1, and it’s not affected by speed techs/trade goods/starting bonuses. But speed bonus from starbases still affect it. Freighter receives a Trade bonus from a Starbase only as long as it stays within a sector where starbase is located.

So, Trade Starbases are more efficient on shorter trade routes. If freighter moves only X squares through current sector, and Trade Route length is Y (Domestic policy->Trade->field ‘Turns’ in table), then starbase gives it’s bonus (X/Y) of the time.
Also, if your Trade Route isn’t vertical or horizontal (only sectors is a matter), then freighter will move to the foreign destination star system and to the source star system by different paths, and in that case you’ll lose 1/2 of the effectiveness of your trade starbases in sectors where freighters move in only one direction.

Code:

|  \
|   \
\    \

  \  |

    *

On a very short trade routes it may be more efficient to build trade starbases in one sector and speed-increasing starbases in others, because they’ll reduce time then freighter don’t receives a bonus from trade starbases. Also, it’s possible to build a ship catapult with a range equal to a (trade route length-1) and trade starbases in the same sector, then freighters will receive a bonus 100% of the time. (Note: it may be trade route length +/-2 because of several factors, but it’s inefficient anyway in most cases compared to standard use of trade starbases). I got a "trade catapult" bringing 80.000 bc/turn but it's cost is to high to be efficient

So, fast tips for using trade starbases:
1) Get a short trade route.
2) It needs to be either vertical or horizontal (say, from sector 1-1 to sector 1-3 or to 4-1).
3) Better if 1 of the planets will be as near the corresponding border of the sector as possible – to reduce freighter travel time through this sector.
4) Systems on both ends must be good economically (you can move some additional population to your system using colony ships, it will be efficient because you can get a significant amount of income even on gigantic galaxy, so even 1% will be important).
5) If you can’t make this trade route, you can give someone a sector with one planet and establish a trade route.
6) Move all your freighters (build new on source planet) to a destination planet, and then cancel all your existing trade routes not on this path.
7) Choose a sector with maximum trade route length through it and build your starbases there.
8) Do it only in late midgame or in lategame.

Effectiveness of starbases.

TradeRouteLength - Domestic policy->Trade->field ‘Turns’ in table. To be more precise, it's number of turns that a freighter needs to move from a source planet to a destination planet, this may be a issue if you are using +speed starbases along the way.
TradeRouteLengthThroughSector – better if it’s 24 (sector size*2, in both directions)
FreighterIncome – Income from one freighter in one turn Domestic policy->Trade->field ‘Value’ if there is no starbases in the sector there current freighter currently present.
StarbaseTradeBonus – Sum of trade bonuses from all starbases in this sector
NumberOfFreighers – on this trade route

IncomeFromStarBases = NumberOfFreighers *(TradeRouteLengthThroughSector/ TradeRouteLength)* StarbaseTradeBonus-NumberOfStarbases*5

Empire Trade bonus multiplies with starbase bonus

Each +50% trade starbase costs 800 production points and 5 bc/turn upkeep cost.
It will pay for itself in (IncomeFromStarBases/(800*NumberOfStarbases))+Number of turns that constructors need to reach place there you plan to build starbases) turns.

Morale

Buildings give it’s bonus *2,8 to planetary morale. Say, Entertainment Network (+20) gives +56 morale.

Empirewide morale bonus (Domestic Policy->Stats->Abilities) gives it’s bonus *0,28 to planetary morale. So, +100% bonus gives +28 to planetary morale. (data from 1.02.042 patch)
(1.04 patch - it gives like *0,23 now, but it also slightly increases with presence of +morale buildings)

PlanetMorale=BaseMoraleByPQ+PopulationMorale+Taxes Morale+BuildingsMorale*2,8+EmpireMorale*0,28

Population Growth

PopGrowthBonus - Domestic Policy->Stats->Abilities -> Pop. Growth

Planet Morale = 100
PopulationGrowsBy=PlanetPopulation*0,06*(1+PopGrow thBonus)

Planet Morale ranges from 99 to 54
PopulationGrowsBy=PlanetPopulation*0,03*(1+PopGrow thBonus)

Planet Morale ranges from 53 to 40
PopulationGrowsBy=0..3

Planet Morale 39 and less
PopulationGrowsBy=negative

Planetary population is capped at 100.000
Planetary population growth per turn is capped at 200.

Revenue

Revenue = FreeRevenue (from planet PQ) + Taxes

If morale is good (there is no penalties to taxes because of morale)

PopulationTax=2*Taxes50 (from table)

Taxes = SpendRate*PopulationTax*(1+EmpireEconomyBonus/2)+(1+PlanetaryBuildingBonus)*GovernmentModifier

**LDiCesare** · May 9, 2003, 14:45

One important thing about economy: The distribution between military/social/research is BEFORE the improvements due to starbases/social projects. This means a spending of 100% can give a benefit or deficit based on the number of improvements you have on the planet and on the number of starbases. I don't know how the total amount of money available is computed, however.

Morale, Taxes and Population – Results

v 0.01

How much % to taxes gives building morale buildings on all planets (54m - +20 Morale building, 14m - +5 Morale buildings) and empire morale bonus (2,8m - +10%) if you are immediately increasing taxes from level 'Tax' field in table to level with the same resulting morale level on planets.

Say, you have only 1 planet with morale of 80, taxes 50%. If you build Entertainment network, you can increase taxes somewhat and get same 80 morale on planet but ~27,42% more taxes (if you got 20 taxes from planet, you'll get ~25).

Buildings - fast tips
v0.9
path 1.03A.057

1) You must have it on all planets (not specifically from the start of course, at the start social spending = 0%), they are most efficient

Soil Enchancement
Habitat Improvement
Entertainment Network

2) Not that critical, but good enough

Banking Center
Manufacturing Center
Anti-Matter Power Plant
Fusion Power Plant (? not sure about that)

3) If you have low morale (low=morale less than 100)

Stadium
Stock Market
Multimedia Center
Trade Center
Teleporters
Harmony Generator

3) If you have some planets with better than average production

Galactic Stock Exchange

5) If you have some planets with better than average production, and you planning or already building/builded starships (not just 1 starship, a lot) there

Advanced Quality Control
Shipyard
Starship Foundry

If you have any other buildings and you don't sure that you need them, it's may be good to disband it (Planetary Screen->'Details' buttion->Click on a project in a 'Compleded Projects' list -> 'Cancel' button.

Note: Don't disband unique projects - trade goods, wonders and special buildings, they are not in this list.

Taxes and Income - Tests and Results

v1.00
patch 1.03A.057

Test 1
Economy bonus from buildings

In test planet population = 1000
Free Revenue is substracted from each number in this table (it was 4 for this planet PQ), so Free Revenue is not affected by economy bonus from buildings.

Tax - minimum Tax Rate where Revenue equal to a listed number - say in 1st coloumn revenue from population with tax 52% equal to 9, and with tax 53% revenue from population equal to 10.

Code:

Econ	0%	100%	200%
Tax	Rev	Rev	Rev
0	0		
3	0	1	
6	1	2	
11	2

32	6		
38	7		
43	8		
48	9		
53	10	20	30
59	11

Results: Economy bonus from buildings gives it's bonus to taxes from population in 1:1 ratio.

Revenue=FreeRevenue+TaxRate*PopulationTax*(1+EconB onusFromBuildings)

FreeRevenue - based on PQ
PopulationTax - based on planetary population
EconBonusFromBuildings - sum of econ. bonuses from buildings

Test 2
