I finally finished this game after a couple close losses with a PA-opportunity that fell into my lap. Wasn't going for it for the most part of the game but i take it.
This was the first time playing on deity and it was quite an experience to say the least.
I don't want to write that much about the actual game, but rather share some of my observations and hopefully it will help other players who are in the same position as i was.
Because these observations are only based on my several attempts at this game so feel free to correct me, if these are not representative for deity/cultural.
As an introduction to the topic i read jesusin's guide and the nice summary from shulec.
My biggest problem in the beginning was getting used to the barbs and the expansionrate of the AI. My first few maps with ghandi were complete fails either resulting in a defeat or being boxed with only desert to settle.
Because i got tired of losing nice starts i decided to go with an less optimal but also lower variance approach.
Therefore i chose mansa musa and went to skirmishers after the first two worker techs.
I feel this is the best leader for "deity-noobs" like myself, because not only are barbs a non-issue, inland sea also has a good amount of commerce potential which helps the financial trait.
The ability to scout, secure good city sites and protect your empire with minimal troops is worth a lot.
The tech- and wonderpace is insane, i was considering to try for oracle as soon as i got used to deity but in my very first test it went around turn 35-40 and i abandoned the idea ever since.
Like Habitus mentioned, getting monopoly techs is key (e.g. aesthetics>alphabet). I made the wrong decision in my first attempts in the case of CS vs Philo. I tend to tech CS especially if taoism was already founded.
But Philo is a much better choice even if your a couple turns late, because the AI seems to skip it if another one got it first and the AI that got it first is very stingy with trading it away.
Basically backfilling CS with philo is way better/easier than the other way round.
I also found out that begging money from the AI isn't as easy as i was used to. I don't know if i begged to much (mostly 50 gold or less) or if my backwardness/ low power rating had something to do with it.
Marble/Copper should be near for NE,Hermitage,Sistine (although its not the end of the world if you lose it) and most cathedrals.
At my skill level, there is still a considerable amount of luck involved. Besides from getting a PA which could be trick, religionspread and the kindness of the AI when it comes to tech gifting can swing the outcome in your favor.
In the submitted game i got another religion by flipping a rival city and got tech gifts all the way to democracy.
All in all i really enjoyed my first deity game. After switching to mansa musa and not losing anymore starts, it provided challenge and entertainment even after several attempts.
It's still a long way for me to play and win regularly on deity but now i know what to expect. Off to Game 10 i guess.
