Science League
From Project Rebearth
The Science League is one of three alliance types available when creating an alliance in Project Rebearth. It focuses on research and exploration, boosting research speed and reducing expedition costs while also raising happiness, at the expense of reduced overall production.
Effects
All members of a Science League receive the following bonuses:
| Effect | Multiplier | Description |
|---|---|---|
| Research speed | x1.2 | Increases University research speed by 20% |
| Expedition cost | x0.8 | Reduces  Food,  Knowledge, and Population costs of Expeditions by 20%
|
| Happiness | x1.1 | Increases Happiness by 10% |
| All production | x0.8 | Reduces output of all production buildings by 20% |
Details
When a player creates an alliance, they choose one of three alliance types: Trade Alliance, Great Federation, or Science League. The chosen type determines the passive bonuses applied to all members of the alliance. Science League has no enactment cost and no lock duration.
The Science League is built around accelerating research and exploration. Knowledge generation at Universities is 20% faster, and Expeditions cost 20% less in Food, Knowledge, and Population, making it significantly cheaper to explore new territory and recover 
Scrap. Alliance members also enjoy a 10% happiness boost, which reduces the risk of strikes and helps trigger celebrations and productivity booms.
The major drawback is a blanket 20% reduction to all production. Every building that produces resources (from Woodcutters and Fisheries to Bakeries and Refineries) operates at only 80% of its normal output. This makes the Science League less suited for settlements that need high raw throughput, and more appropriate for mature towns with established supply chains that can absorb the production penalty.
Strategy
Science League is the best choice for players who prioritize expansion through Expeditions and long-term Knowledge accumulation. The 20% reduction in expedition costs compounds over many expeditions, yielding more Scrap and basic resources per unit of investment. Faster research also means earlier access to advanced upgrades and technologies.
The happiness bonus provides a passive quality-of-life benefit, reducing the need for happiness-boosting Choices like Lavish Rations and freeing up policy slots for other options. However, the 20% production penalty is steep. Settlements in the Science League should plan for larger production capacity to compensate. More Fields, more Woodcutters, and more processing buildings than would otherwise be needed.
Compared to the Trade Alliance, which boosts commerce, or the Great Federation, which offers balanced production and safety, the Science League rewards a more exploratory and research-driven play style.
