Bloc Alignment & Spheres of Influence

The Cold War era layer tracks two related things: how drawn a nation is toward each pole (alignment) and which patron the nation actually belongs to right now (its sphere). Alignment is the cause; sphere membership is the effect that follows from it.

Alignment shares#

Every nation carries a share (0-100) toward each pole in the current era, plus an uncommitted remainder. Shares across all poles and the remainder always sum to 100. The gap between a nation's top pole and its next-highest is its lead, and lead is what most thresholds are measured against:

• 85 lead (locked). A nation this committed is immovable by ordinary passive drift; only a deliberate influence play can shift it further.
• 20 lead or below (non-aligned band). A genuinely uncommitted nation resists drift at half the normal rate, so it does not get accidentally nudged into a bloc.

Joining and leaving a bloc#

Whether a nation can join, or is drifting toward leaving, an alignment-governed organization (a bloc, alliance, or similar channel) is measured on the nation's share in that org's pole specifically, not its overall lead:

• Share at or above 60 means the nation may join.
• Share at or below 40 means an existing member is heading for the door (flagged as wanting out).
• Between 41 and 59 is a deadband. Nothing happens here. This stops a member flapping in and out of its bloc on a few points of ordinary drift.

A nation has to hold past one of these thresholds for a sustained run of turns (half a game year) before the world actually acts on it, joining, leaving, or feeding into bloc stress. A one-turn spike does not trigger anything.

The Non-Aligned Movement is a special case: it has no pole of its own, so its "share" is read off the uncommitted remainder against the same 60/40 gates.

Passive drift#

Alignment shares move a little on their own every turn, but this background drift is deliberately small: a player's own influence play always outweighs it. A few things shape how it lands:

• Opposing pulls on different poles cancel out before anything else is applied, so only the net direction matters.
• Pulls toward the same pole simply add together.
• Movement in a single turn is capped, and the cap is larger for a nation currently caught in an open crisis, so a live flashpoint can move faster than routine drift.
• Standing membership in an alignment-linked organization exerts its own small constant pull toward that org's pole. This pull alone can carry a nation up to a ceiling well short of the locked threshold; getting a nation past that ceiling and toward being locked in takes a deliberate play, not just sitting in the organization.

Bloc stress#

A bloc's own cohesion is modeled separately from any one member's alignment. An alliance that expands fast does not automatically defend everything it holds as well as a smaller, settled bloc would. Stress is a single 0-1 gauge built from three things about the bloc's own membership:

• Contested members. Members a rival pole is actively pulling at cost attention; members nobody is contesting cost nothing.
• Members heading for the door. The same sustained "wants out" signal used for leaving thresholds.
• Recent accessions. Members who joined within roughly the last quarter game-year are still being digested. This cost decays over time, it is a transition cost, not a permanent tax on being large.

Raw member count is deliberately not an input: a large bloc of settled, uncontested members is not penalized just for its size.

Stress reduces how effectively the bloc's own plays land, up to a cap: a fully stressed bloc is meaningfully impaired but never completely inert. It falls into three player-facing labels: Settled, Strained, and Overextended. Stress is self-correcting; it falls as contested members settle and accessions finish digesting, with no action required from anyone.

Open World > International Organizations, select a bloc, and use its Influence tab to see pole shares, targets, and bloc stress. Diplomatic actions such as membership proposals use the acting country's per-turn diplomatic-action budget.

What this means for you#

• Watch your bloc's stress label before pushing to add more members fast. A string of new accessions or a run of contested members will blunt your bloc's own plays for a while.
• A member sitting in the 41-59 deadband on your pole is not actually at risk of leaving yet; do not waste effort trying to "save" it.
• A member below 40 for a sustained stretch is a real defection risk and will start showing up in your bloc's stress.
• Passive membership alone will not lock a nation into your sphere. If you want a nation genuinely committed (past the locked threshold), you need deliberate influence plays, not just organizational membership.
• Crossing into a new alignment era re-maps every nation's shares onto the new era's poles once, automatically; a pole that has no successor in the new era returns its share to the uncommitted pool rather than vanishing.
