This map is a quite general and common, still above average due the land available to human player. The biggest or rather common problems in the opening are happiness and commerce. The gold site is nice, but due to the serious barbarian swarm, I can only managed to grab it ~2000BC. Most of the decent sites are far from capital, which took a lot effort to settled since you need an Axe to guard and workers to preroad to the city. And yes, each commerce shines in the early stage.
I started the total war in 740AD with 30+ cossacks to invade German, who was the biggest AI. I bribed Bismark to DOW the most advanced HC some turns ago. However, I did not have techs to bribe HC leaving the war, which cause Bismark to vassal to HC. One of the annoying feature of Warlord is that AIs won't talk with you for a long time no matter how much loss in the war. As a result, I have to DOW his Master HC immediately, in ~900AD, German was complete gone and my cossacks enter the Incan empire, then I saw Riflemans on a hill city.

That's not a surprise in Warlord deity. The thing surprised me that time was that my empire was 100g deficit even at 100% gold slider.
Except the poor Vicky, who was DOWed by Monty and HC, I had to fight all other AIs having Riflemans.
The game was ended unexpected. I aimed for Conquest victory. In 1250AD, I DOWed the last AI Gandhi while still fighting with Monty, this action immediately added 5+ angry faces in my whole empire.

Next turn, the victory screen popped up and Monty was willing to capitulate.
Winning Warlord Deity seems to be a lot faster, at least I have not won BTS deity that early.
