I am sure Diety is a different matter entirely. This is at Monarch.
Anyway I took the advice offered and promoted the chariots for strength, attacked the metal city first with about twenty chariots, and they just had the one source of metal so I got lucky there.
I won the war but had economy problems and lagged in tech because I was whipping chariots I guess.
Attacking your first city on Monarch with 20 chariots sounds like the reason your economy crashed. This could be justified if the AI is choking you settling with a hilled city... otherwise, this is a poor use of resources. Try to strike to the heart of the the AI empire, the capitol. First, get intel to know how many troops are in the first city:
- Use open borders
- Promote a 5/2 XP chariot with Flanking I and Visibility. (Barracks and two XP from killing barbs.
- Guess that his capitol is nearly empty once you see a settler leaving the capitol
Take a cease fire, which stops the war with 0 turns of peace. Heal, and declare war again right away.
You should be able to mow down one AI and have experienced troops ready to harrass or even take out a second AI.
Consider attacking with 6-9 chariots to take 1-2 cities. This will be several turns earlier than with 20. Take a cease fire and wait for the next 6-9 chariots to show up and finish the AI off.
