The Production Queue
Slots, not a line — everything in a slot runs at once.
PARALLEL LANES
Every kind of production has its own lane, and lanes never compete with each other — a city can build, train, produce missiles and research all at the same time. Inside a lane each item starts its own timer the moment it's queued; the number of slots is how many can run at once, and a request beyond that is refused.
