production Building Comparison
Crystal Mine vs Gas Extractor
Comparing the Crystal Mine and Gas Extractor, both production buildings in Starforge MMO. Base plots and energy upkeep are scarce, so use this to decide which structure earns its slot first.
Build & Output Comparison
| Attribute | Crystal Mine | Gas Extractor |
|---|---|---|
| Max level | 20 | 20 |
| Base cost | 150 metal, 200 crystal | 300 metal, 150 crystal |
| Upkeep | 12 energy | 15 energy |
| crystal production / level | +30★ | — |
| gas production / level | — | +15★ |
★ marks the higher per-level output. Compare against your base's current bottleneck before committing a plot.
Crystal Mine
Harvests crystal lattices from geological formations.
Gas Extractor
Atmospheric gas harvesting platform.
Which Should You Build First?
Both are production buildings, so the choice depends on your current bottleneck. Prioritise the structure whose highlighted per-level output addresses your scarcest resource, and weigh that against its energy upkeep — a high output that drains your power grid can stall the rest of your base.
