I've played through to Astronomy tech, have done virtually NO TECH TRADING. I'm following Justinian's stratergy *I think*, or many others, from Deity, and not trading with the AI's to slow them down.
MM is out right tech leader, with Cyrus behind.
First Difference, VIKINGS DESTROYED in BC's...
Aggressive settling of available land, but only one on 2nd main land mass, as its costing me 7 gold /turn, and going for Quality over quantity there. Optics in 820 AD, much slower...Astronomy in 1260, but most bar Cyrus, DON'T have Optics YET....hehehe
Suraveyman, is BEHIND...and DEAD.
My plan from here, is Build and East INdiaman, Take Ragnars old capital, (only city on land mass), build forbidden palace there, and make it Main land No 3. let MM build Versilies as he has 3 religions, should be going for a Cultural win, and will be easy meat come Grenadiers.
I didn't trade for the USELESS religion tech's (free religion or Nothing) why you did
I'm still yet to settle Iron, and have traded stone for 6 gold/ deer as only foriegn trade...Hammers from Citizen specialists when hit happy cap, only 1 GP farm as per rules.
Real struggle for hammers, researched all of Astronomy as I popped 2 Preists when I wanted Scientists...Oh well hammers and gold from settling.
