Tile value is determined by yield, travel time, reinforcement access, and exposure rather than yield alone. Source
Evidence status — inferred: Unless noted otherwise, mechanics are verified against the installed patch 11.73 guide.
Rank a target on four axes:
- Yield: production/terrain bonuses and rare-metal table.
- Reach: travel time from a real shipyard, not visual distance.
- Support: who can reinforce and supply it?
- Exposure: how many hostile launch bases can reach it before your faction can?
A modest tile inside a reinforcement triangle is often worth more than a spectacular tile hanging alone in enemy space.
