Stone Biome
From Project Rebearth
The Stone Biome is one of four biomes in Project Rebearth. It covers mountainous and rocky regions of the world, where 
Stone is the dominant resource. Settlements in the Stone biome benefit from the highest Stone and 
Ore production rates in the game, making it the premier biome for mining, metalworking, and advanced production chains.
Overview
[edit]The Stone biome is associated with rocky, mountainous, and arid highland landscapes. Stone serves as both the primary resource and the construction material for all buildings in this biome.
Construction
[edit]Buildings in the Stone biome cost Stone as their primary resource. For example, a Shack costs 35 Stone, a Cabin costs 80 Stone, and a Town Hall costs 1,000 Stone plus 500 
Wood, 10 
Tools, and 20 
Glass.
Housing Upkeep
[edit]The Stone biome has standard housing upkeep, identical to the Wood Biome. A Shack consumes -1 Wood per day, the same as the Wood Biome, roughly ten times higher than the Earth Biome (-0.1), and half the rate of the Arctic Biome (-2). 
Food consumption remains the same across all biomes.
| Housing | Wood/day (Stone) |
Wood/day (Earth) |
Wood/day (Arctic) |
Food/day
|
|---|---|---|---|---|
| Shack | -1 | -0.1 | -2 | -1.5 |
| Hut | -1.5 | -0.15 | -3 | -2 |
| Cabin | -2 | -0.2 | -4 | -2.5 |
| House | -2.5 | -0.25 | -5 | -4 |
| Residence | -3 | -0.3 | -6 | -5 |
| Villa | -3.5 | -0.35 | -7 | -6 |
Resource Production
[edit]All biomes have different production rates and the table below compares key building output across all. Values in bold indicate the highest rate for that building in the Stone Biome.
| Building | Resource | Wood Biome | Stone Biome | Earth Biome | Unit |
|---|---|---|---|---|---|
| Woodcutter | Wood |
30 | 15 | 5 | /day |
| Nursery | Wood |
5 | 2 | 1 | /day |
| Tent | Wood |
5 | 3 | 1 | /day |
| Saw | Wood |
20 | 20 | 20 | /day |
| Quarry | Stone |
0.01 | 0.03 | 0.01 | /m²/day |
| Stone Crane | Stone |
20 | 30 | 10 | /day |
| Claypit |  Earth |
0.01 | 0.01 | 0.04 | /m²/day |
| Clay Crane | Earth |
20 | 10 | 30 | /day |
| Iron Mine | Ore |
40 | 100 | 60 | /day |
| Foraging Hut | Food |
5 | 5 | 3 | /day |
The Quarry produces 0.03 Stone per m² per day in the Stone biome, three times the rate in other biomes. The Stone Crane produces 30 Stone per day, also the highest of any biome. This abundance of Stone makes the Stone biome ideal for large-scale construction and trade.
The Iron Mine produces 100 Ore per day, the highest of any biome and more than double the Wood Biome's rate of 40. This makes the Stone biome the premier location for Ore extraction and downstream 
Metal and Tools production via the Refinery and Tools Workshop.
The Woodcutter produces 15 Wood per day, half the Wood Biome's rate of 30 but three times the Earth Biome's rate of 5. Unlike the Wood biome, the Woodcutter in the Stone biome does not consume Tools.
The Foraging Hut produces 5 Food, 1 Wood, and 1 Earth per day. The Food output is tied with the Wood Biome for the highest among all biomes.
Strategy
[edit]The Stone biome excels at mining and industrial production. The Quarry and Stone Crane provide abundant Stone for construction and trade, while the Iron Mine at 100 Ore per day enables strong Metal and Tools supply chains. Settlements in the Stone biome are well-positioned to become manufacturing hubs, supplying Tools to other biomes through trade.
Housing upkeep is identical to the Wood Biome, with standard Wood consumption rates. The Woodcutter produces a moderate 15 Wood per day — sufficient for basic needs but potentially limiting during rapid expansion. The Saw produces 20 Wood per day regardless of biome, providing a consistent supplement at the cost of -0.2 Tools per day.
The primary weakness of the Stone biome is its low Earth production. The Claypit produces only 0.01 Earth per m² per day compared to 0.04 in the Earth Biome, making Glass production more dependent on trade or large clay pit areas.
