Which Should You Build First?

Both are alliance 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.
