Abbey of Kings at 2:10 (0:00–4:40)

Age up at 2:10 with the 2 gold villagers; during the age-up, 4 on stone, 8 on wood and 4 on food pay for the second Town Center.

0:00 — 6 villagers on sheep; scout for sheep right away.
0:15 — When the first villager is 75 % produced, 1 sheep villager builds a House, then goes to gold.
0:20 — The first produced villager goes to gold and builds a Mining Camp. Rally on sheep until 10 on sheep.
2:10 — The 2 gold villagers build the Abbey of Kings. 4 sheep villagers to stone (Mining Camp), 2 to wood (Lumber Camp); rally on wood until 8 on wood.
4:00 — Rally on sheep until 8 on sheep. Use the Scout to locate deer packs for the second Town Center (near gold or wood). 1 wood villager builds a House.

Start the second Town Center at 5:00, then rally both on gold. Start The White Tower at 8:40: Age III at 10:00 with the economy already booming.

4:40 — Age II: the 2 Abbey builders go to gold. Use the King to harass.
5:00 — 4 wood villagers and 4 stone villagers build the second Town Center.
5:25 — Rally both Town Centers on gold until 10 on gold. 1 wood villager builds a Mill for the economic upgrades.
5:50 — A second deer pack near the new Town Center: Survival Techniques. Otherwise Wheelbarrow and Horticulture. 1 villager builds Palisade Walls where protection is easy.
7:00 — When the sheep run out, the sheep villagers build Farms.
8:30 — Pick the spot for The White Tower. Double Broadax, Specialized Pick, and Wheelbarrow + Horticulture if Survival Techniques was taken.
8:40 — 10 villagers build The White Tower.

Hit a timing when the enemy has to transition to farms: your economy and production are already in place.

10:00 — Monastery for 1 or 2 relics, Blacksmith for upgrades; start the Farm transition.
13:00 — Lumber Preservation, Shaft Mining, Fertilization and military upgrades. Harass, then recover with Abbey Healing. Finish the Palisade Walls; Barracks, Archery Range, Stable.
15:00 — Keep the military transition and the harassment: the economy is booming, trade units freely. Keep building Farms, and an Outpost before every fight.

For opponents who do not attack much: you reach Age III without production buildings, and The White Tower defends by itself.
Answer with The White Tower: 1 TC all-in → Man-at-Arms or Knights with a Barracks or Stable; mass Horsemen or Longbowmen → Knights or Longbowmen; mass Man-at-Arms → Crossbowmen; Horsemen and Knights → Spearmen or Crossbowmen.
Avoid massing Longbowmen early: they eat the wood you need for the Farms.
Put the second Town Center on a deer pack: Survival Techniques then beats the Farm upgrades.
