"about this review - i didnt needed any workers because cities were growing already nicely. Well i had immortals but at that time i should have replaced them with something else, im not sure with what."
You must have workers and lots of them. You need to make roads on all tiles. You need to put down mines or irrigate. You had no water so irrigation will have to wait until you have Electricity.
You need to have these roads and mines as soon as you have a citizen working a given tile. Workers and settlers were going to be some what problematic for you as you had no water. Still you have to make them.
Cities were not growing nicely, in fact you had no cities, only towns. A city is 7 to 12 in size. Growing nicely means, to me, gaining a pop at a +3 or there about rate.
You needed a lot more towns, that is how you pay for research and units. You really had nothing to replace Immortals with at that point. If you had a few spears to go into battle with those Immortals, you would do better.
Do not spread out your forces. That is what the AI does, say you had 8 Immortals. If you had4 spears with them you could have two stacks. 4 immortals and 2 spears in each.
They would take down those towns, if you get there before they get pikes. Hold the town or raze it. Move on to the next and the spear would defend, if the stacks were attacked.
"Another matter is im not sure how ai was advanced, i guess i abit more in tech tree.
How long you guys play one match vs ai?

"
You were down on Feudalism as I recall. This shows how weak the AI plays at Chief. You would have been eliminated even at Regent with those holding at 970AD.
I would expect most play until they either have won or lost or the end is in sight. If you mean in terms of real time, that can be up to hundreds of hours in a like 250x250 with 30 civ play a conquest only Always War.
I would guess 40 hours is common for a std maps.
"p.p.s. i will place few more savegames then i finish my match.This time its somehow a fight for land - that means i cant simply go fighting because i wont speed up with settlers and workers.

"
I am not sure I understand this one. Most games will be a fight for land. I again suggest you read one of the low level SG's. Pick one that was completed. You could also just read the thread in the Strategy Articles I wrote as a tutorial for Regent players.
You will see some concepts and tactics explained that should help you.
