I'm relatively new to Touhou and i haven't played Alpha Centauri for a long time, so forgive me.
Since there is a Civilization IV Touhou mod (haven't plated it yet), i wondered how it would apply to Sid Meier's other masterpiece: Alpha Centauri (SMAC).
SMAC backstory taken from Wikipedia:
According to the storyline of the game, humanity destroyed itself through war, famine, pollution and poverty, but before complete self-destruction the U.N. launches an enormous colonization starship called Unity. The Unity is destined for a planet in the Alpha Centauri system. This planet is named "Chiron", but is often referred to as just "Planet". This plot is loosely based in the end of the first Civilization games, where one of the victory conditions was to send a spaceship to the Alpha Centauri system.
However, before the starship reaches Planet, forty years into the journey, the Unity suffers a core malfunction. As a result, many of the crew awake and proceed to fix the malfunction. During the repair operations, the captain of Unity, Garland, is assassinated by an unknown assailant. The rest of the crew is awakened soon after.
When news of the assassination spreads, the crew panics, and the ship begins to break apart due to mishandling. Seven leaders take up the challenge of leading a faction onto Planet by use of colony pods. (The game's video introduction depicts an eighth escape pod separating from the Unity, only to explode shortly thereafter.) As Unity breaks up in high orbit, supplies, components, and factions spread everywhere. After the colony pods land, the player comes in to take control and aid their faction to victory over the others.
As for our heroines (my interpretation):
Since the Earth was dying, the dormant spiritual and magical energies were dying too, and Gensokyo was no exception.
With the help of many powerful Youkai, Yukari put the residents of Gensokyo and some of relative realms (Underground, Hell and others, while Shinki simply "packed" Makai) to statis-sleep and placed them in the pocket dimension. She then boarded the Unity.
When they arrived, Yukari and others used the rich dormant energies of Chiron to create another Gensokyo.
Where they proceeded to fight for dominance for whatever reason.
So here's my take on our arm-pit miko:
FACTION: Hakurei Shrine
LEADER: Reimu Hakurei
BACKGROUND: Shrine Maiden of Hakurei Shrine
AGENDA: Peacekeeping survivalist
STARTING TECH: Divine equivalent of Applied Physics (Effective Danmaku), Divine equivalent of Field Modulation (Force Fields)
Modifiers (a quick rundown for those who haven't played SMAC):
Economy - How much energy is produced;
Efficiency - How much energy is consumed;
Support - How costly is the units upkeep.
Morale - How good the units are in battle
Police - How likely the residents are to riot and how much they are tolerant to the use of military for police functions.
Growth - How quick population increases.
Planet - How damaging the residents are to the local nature.
Since Gensokyo was mostly rural, I think everybody has at least +1 in this
Probe - How good your espionage is.
Industry - How much material resources are used to produce things.
Research - How quickly you are at researching tech.
+1 PLANET - Near-Universal Gensyoko trait.
+2 PROFICIENCY or +2 INDUSTRY - Living with nearly no donations will teach you to be efficient with your resources.
-2 GROWTH - As a result of donations-free life
-1 SUPPORT - Reimu is new to this leader business.
Faction's unique traits:
+25% Combat proficiency
+1 Nutrient (food) resource bonus - As a result of Reimu's "Grass = Emergency food" mentality.
Less penalties for PLANNED economics model.
Free Magic\Mana\Divine energy storage at every settlement as soon as required tech is researched
Free Defense Barriers at every settlement as soon as required tech is researched
Special units:
Shingyoku:
Special abilities: Walking PSI-Gate - Shingyoku acts as the teleporter gate for your units.
Dimensional Rift - 25% chance to clone selected unit.
Misc:
Unity pods (SMAC goody villages) are replaced by sealed storages.
Kotohime:
+2 Police
POLICE STATE policy
or
Constant stat changing (like Balsheraph leader's madness from Civilization IV mod Fall from Heaven II)
Moriya:
FUNDAMENTALISM policy
+2 PROBE - It's a Moriya Shrine Conspiracy
Myouren:
Sea settlements
Access to WEATHER PARADIGM Secret Project thanks to Unzan.
EUDAIMONIC (happy co-existence) future society
Team Shanghai Alice:
Like the joke faction Firaxians from Alpha Centauri they have no advantages and no disadvantages, unless you count a very, very, very late tech: Singularity.
