That was actually very good ! :D I don't know if you even need the 4 vill card there, but it worked well. Nice boomy playstyle =) You could experiment saving the 4 villager shipment, and taking 8 jans card straight after 5 spahi. Or even a fort. You had the right side of map in your control, why not take even more?
1500 f during ageup to IV is easy to get. Maybe get wood from trade posts and gather food/coin, and get guard jans asap? Wood is slowest to gather so take it from the tp eco. And also you have that nice 15 jans for 1000w tech in the Unique Church :D
Overall very solid stuff, i'd like to see this strat in a game where enemy puts pressure on you. :)
