Algorithm (Clash of the Timelines):

Location

 * Defending Nation: +10
 * On Border: +8
 * City near border +6
 * No former presence, core of army away from battle: +0

Power
Land is always applicable, Navy is only applicable when an attack on the coast is made. Air attacks must be plausible, if you have no air bases in the region you can't use it.
 * Large aerial assault capability +3.5
 * Large naval assault capability + 3.5
 * Large land assault capability +3.5
 * Medium aerial assault capability +3 (if enemy has no aerial power) +2 (if the enemy has aerial power)
 * Medium naval assault capability +3 (if the enemy has no naval power) +2 (if the enemy has their navy stationed in or around the location)
 * Medium land capability +3 (if three or more times larger than enemy) +2 (if less than three times larger than enemy)
 * Small aerial/naval/land capability: +1
 * Land, aerial, and naval is compounded. If you have large naval, medium air and medium land, your score is 9 or 7. You cannot have medium aerial and large aerial at the same time.
 * Power is averaged in a coalition war.
 * Power is a multiplier for development.

Tierless
Any nation not listed above has no tier.

Points: Power Caps:
 * Tier 1 nations get plus 20
 * Tier2:+15
 * Tier 3:+10
 * Tier 4:+5
 * 1 tier above enemy:+2
 * 2 Tiers above enemy:+4
 * 3 Tiers above enemy:+6
 * 4 Tiers above enemy:+8
 * Tier 1 invading a tierless nation: +10
 * These are subject to change over time, though there are restrictions on movement. To push a nation out of a tier (IE you want to enter tier 1 or 2 but they are full) you need to have a larger economy and be all around better than them.

Each Tier has caps on its power:
 * Tier 1:No Cap
 * Tier 2:8.5
 * Tier 3: 6
 * Tier 4:4
 * Tierless:3

Strength

 * Your amount of troops divided by 100,000 (Ex: one million= +10)

Motive

 * Economic (Gains land, resource, etc): +4
 * Defending territory not owned by nation more than 20 years: +6

 * Counter attack: +5
 * Modifiers:
 * Non-democratic Government supported by people: +4
 * Democratic government supported by people: +5
 * Government not supported by people: -5
 * Troop Morale high (requires motive over 10, chance over 6, and stronger development scores in at least one category): + 10
 * Troop Morale low (any of the above:  lower development scores in all categories, recent war penalty over 16): -10
 * Fighting Guerrilla War: -10 attacker, +2 defender

Landscape
Knowledge of landscape: +10 for in one's homeland, +5 for warring in an adjacent nation, -1 for low knowledge of an non-adjacent lands which are on you continent, -10 for no knowledge of a distant realm that is not even on your continent and in polar regions (unless the attacker is also polar) -6.
 * Urban warfare: Attacker -2, Defender +2
 * Storming on to a coastline from the sea or on to an island, the attacker - 4 and defender + gains 5.
 * Storming in to a desert, high mountains, or jungle the, attacker -3 and + defender gains 4.
 * Armed expatiation in large extremism climates like Greenland, Niger, Nepal and Amazonia will also be very slow due to logistic and climate problems for any wood-be invader. In this case the defender gets an advantage of +5 and the attacker gets a disadvantage of -6

Allies

 * Leader Nations: +10 each participating


 * Military aid: + 5 each participating


 * Supplies: + 4 each participating


 * Cultural Support: +2 each participating


 * Vassal: -2 each participating


 * Vassal is an L:-5


 * Withdrawal: - 2 each nation which was participating and then left


 * ex: China (L) Vietnam (M) France (S) Britain (C) Japan (MV) Korea (SV) = 10 + 5 + 3 + 2 + 3 + 1 = 24


 * Please note that Vassals CANNOT give Cultural aid.

Recent Wars
Each war in the past 15 years where nation was a...
 * Leader: -8


 * Military aider: -4


 * Supplier: -2

Military, Economic and Infrastructural development
Military, economy, and Infrastructure can be developed as the game progresses. Each turn you may develop 2 of the categories. '''Infrastructure applies only to defenders and is not multiplied by power. ''' Development points last 20 turns each.

NPC development is a bit confusing. NPCs develop in this order: Infrastructure-Military and Infrastructure-Economy, Giving them 10 points in Military adn economy and 20 points in Infrastructure.

 * 400,000 * 0.95= 380,000 (Winner)
 * 300,000 * 0.80= 240,000 (Loser)
