I started a game
Cyrus, Marathon, Shuffle, Noble
Heres my start
[ snip ]
I was wondering what should my starting tech path be? Mining or AH or fishing?
Slobberinbear's path is good. Why it is good is shown by the matching build order. As far as I can tell, on marathon, the cost of techs and units are:
Fishing: 120
Animal Husbandry: 300 (reduced to 180 due to prerequisites?)
Mining: 150
Warrior/Scout: 30
Work Boat: 60
Worker: 120
Grow 1->2: 66
Grow 2->3: 72
Right now you produce 2 food, 2 hammers and 9 commerce. It'll take you 40 turns to produce a worker, 17 turns to grow, 15 turns to train a scout/warrior and 30 turns to build a boat (you'll have its benefit by turn +31).
It takes you 14 turns to research fishing, 20 to AH and 17 to mining. So you can have a worker start improving the cow on turn 42, and be finished on turn 54. You'll still be size 1, but produce 3-4-9. It will now take you 8 turns to finish the boat, but it'll be 22 more turns until you can work more than the cow (switching to the fish gets it done faster, but then you've wasted the early cow).
If you start with fishing and a warrior, you'll finish the warrior and start the boat on turn 16. You grow the next turn to 2-3-9. Say you finish the boat on turn 37. Now you know fishing and mining. On turn 38 you start working the fish, and produce 5-2-11. Also, you have enough food surplus to work both gold mines already, so build the worker now. With all that extra food, it'll be built faster than the second boat. You'll have your worker around turn 56. So around turn 55, both options have improved tiles, but the fishing option has higher population and research.
Only thing I disagree with is bronze working. I'd go Fish - Mining - Wheel (you will need the happiness boost early) - AH - BW - Pottery. But that's details. If you can get BW before the worker has finished the gold mines, by all means go for it.
