production Building Comparison
Antimatter Refinery vs Crystal Mine
Comparing the Antimatter Refinery and Crystal Mine, 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 | Antimatter Refinery | Crystal Mine |
|---|---|---|
| Max level | 10 | 20 |
| Base cost | 4,000 metal, 2,000 crystal, 1,000 gas | 150 metal, 200 crystal |
| Upkeep | 80 energy, 40 crystal, 20 gas | 12 energy |
| antimatter output / level | +2★ | — |
| refinery efficiency / level | +0.03★ | — |
| crystal production / level | — | +30★ |
★ marks the higher per-level output. Compare against your base's current bottleneck before committing a plot.
Antimatter Refinery
Processes raw antimatter particles harvested from stellar phenomena into stable fuel-grade and weapon-grade antimatter variants used in the most advanced drives, weapons, and exotic structures.
Requires tech: mining 3
Requires building: fusion reactor
Crystal Mine
Harvests crystal lattices from geological formations.
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.
