|Welcome to Earth 2025 Information Page!|
Always under construction. Until Earth 2025 stabilizes (A.K.A. stops changing so much) I will probably not be updating it as much. School work, my life and also Study are taking up most of my time. I may begin keeping this page uptodate in the summer. I will still sometimes add links to other pages.
Added 1997-Dec-19 The amount of food military consumes.
added 1997-Dec-25 Beta Guide to types of Buildings.
added 1998-Feb-14 Rewrote Gaining Networth section.
added 1998-Mar-21 Tech produced in one turn, recieved from Daniel Wahlqvist
added 1998-July-25 Several Links
added 2002-Jan-26 Added link to Daniel Eloff good page.
This webpage is designed for YOU. If there is any information that YOU want to see here email me I am no longer interested in email about Earth 2025
Thanks to blackout (who wrote most of the original gaining Networth section) and catmaster for some of the tips. I am willing to include any submissions you send me if I think they are worthwhile.
I am interested in any information about the game that is not in solaria docs.
Note: These are my recommendations, not the law
The documentation that Solaria provides gives a good overview of how the game works. Reading it all will help greatly. It is available at Instructions
The goal at this stage is to fill up those empty acres and build up enough economy to be able to fill up the land you will explore.
First, change your tax rate to 20%-35% and change your economy to what you want it to be.
Begin by building 5 Enterprise zones and 5 Residenceses. You will need about 10-15 farms to feed the population on a hundred acres. When you don't have enough money to build as many buildings as you can, build construction sites. Continue building contruction sites, enterprise zones and residences (and if you want industry) until the hundred acres are filled. Keep the number of enterprise zones and residences about constant.
A somewhat common newbie mistake is to begin attacking in this stage. Don't attack. It wastes military, annoys people and gets you less land then you would get if you explored.
When you have filled up the land, you are ready for the next stage.
The goal at this stage is to gain technology and to build up land. Only with a solid technology base will your country be able to thrive. The amount of land you have is a huge factor in your success. Large amounts of land can produce the most military.
Prior to massive exploration you want about 100 enterprise zones, 90 residences, 30 farms, and 70 construction sites. (You will have to explore about 200 acres to do this
Explore until you have about 2000 acres. Now you are ready to gain technology.
There are three ways to gain technology:
This is the first stage that you have to worry about defense. Before you begin to worry about research first build about 50 or so industries. Produce lots of turrets and a little of everything else (I personally set it to 60% turrets, 10% everything else). These industries will steadily pump out military with out you having to worry about them.
The maximums (if Patel hasn't changed them yet) in technology are Military 83%, Medical 67%, Business, Res, and Ag 200%, Warfare 10%, Weapons 150%, Industrial 150%, and SDI 100%.
Continue to gain technology until you have come close (with in a few percent) of maxing out the technologies. Then double the tech levels of the technology that is vital to your strategy (for example if you are planning on selling military, double the Military tech levels.).
When you are done gaining technology you are ready for the next stage.
The Goal, Become ranked number 1
You have probably been playing for about 1-2 weeks. Your country is now begining to become strong. You have a solid technological and economic basis to do what ever you want. Now you have to choose how you want to try and win the game.
Basically there are two over all strategies:
There are three main nonmilitarist ways to gain networth:
Use the daily challenge and logout after turns. This will give you 4-5 more turns a day.
Also, try tweaking your tax rate. Start at 25%. There is a perfect balance where you can make the most money, though. So, you might want to lower it a little.
Note: all the formulas are ±1% and ±1.
Note: have not update for Jan 20 server reset.
ARC=Old formulas no longer used
S2=server 2 and server 1 (Note: I haven't checked all the formulas on server 1 yet or server 2 Jan 20 reset)
TR=tax rate (example .25 for a 25% tax rate)
Lab=total number of research labs
EffectProductivity gotten on the Research page. For Example if it said Max Productivity: 105% of Normal then EffectProductivity=1.05
EffectPopulation is similar to Effect Productivity
POP±5=12*(1-TR)*(A + 2*RE)*EffectPopulation
PCI=floor(EffectProductivity*(22.75-25*TR)*(1 + 2*EZ/A)*(democracy 1.15:Republic 1.08: Monarcy 1:Dictatorship .87: Tyranny .83)
Networth=95*A + 70*(A-UA) + 2*troops + 2.5*jets + 2.5*turrets + 8*tanks + nuclear + chemical + biotech + POP/3 + money/10000 + Sum_of_Tech_Levels
S2:amount of construction/turn + -1=floor((.33*CS + 5)*(democracy 1.1:else 1))
cost of construction=2*A + 1500
production of farms=EffectAgriculture*(45*Farms + UA*4)
cost of military=.15*troops + .1*jets + .1*turrets + .53*tanks + .8*spies
cost of land=4*A
tech produced in one turn = 0.4*lab(1 - (1 - lab/A)/2) + 3
Thanks for the above formula, Daniel Wahlqvist
ARC:amount of construction/turn=floor((.5*CS + 5)*(democracy 1.1:else 1))
ARC:purchase cost of military=cost*(1-.5*MilitaryBases/A) (In other words the effect of military bases (was wrong))
ARC:cost of military=0.08*troops + 0.097*jets + 0.097*turrets + 0.255*tanks + 0.3*spies
If you know of anymore formulas or think these are wrong contact me at I am no longer interested in email about Earth 2025
I have obtained these by statistical analysis.
This info is archaic
About industry: Did you know that industries can produce military even when the country can not pay the expenses on it? I lost a game because of that fact (I had destroyed his economy by guerrilla warfare but could still not beat him in regular attacks).
In my experimental country I found out that raising taxes to a level (like 35%) will give a higher population than lowering taxes to the same tax level. Tax Pop up to 35 % from 30% 803 down to 35 % from 40 % 799
There is not much difference but it is a interesting fact.
It never goes past 200% on population/economy. 67% for the first two. 10% for warfare and 100% for SDI.
This section is designed to be a more understandable version of the formulas. I have receive several emails saying the formulas are not understandable. I hope this section clears up some of the mystery. The formulas are more accurate since I have oversimplified several times.
If you don't understand any part of this section please email me at I am no longer interested in email about Earth 2025 and I will work on making it clearer and try to explain it to you.
I propose a new way to decide how changes are made.
(Basically: Have several different types of games and keep the most popular)This method has the advantage that the PLAYERS choose which variations are used. The previous way of listening to the players to decide what variations to make has been to listen to who makes the most noise. My proposed method would allow the players to choose by playing their favorite variation.
Proposed game types (variations):

Think its a good idea? Create a updated webpage about it.
