Great! another game to break our heads over. And epic... but why not marathon ;-) *edit* not Noble but Prince will offer a nice challenge*
Lots of food, low shields though. Clearing all forests will hurt in production a lot. It will support many specialists, ie GP factory, but limited wonders. Judging from the yield map, we are next to the coast and lakes, so lighthouse should be possible making lakes worth 3 food. That means we are looking at +9 food (+2 city, +3 sheep, +2 wheat, and +3 for each laketile) before building the first grassland farm. You'll need agriculture, animal husbandry and sailing to unlock them though. Finding health bonuses early will be most useful. Of course we have sheep and wheat. Until Londen can really expand we can use the rabbit-like breeding of population with the Slavery civic for extra production .
The tropical climate will show more of this pattern of high food and low production. Founding a few production cities where possible will help. Locations of city 2 onwards could be problematic. Ice to the north and desert to the south.
Also important to note Lakes map have no world wrap, so civs in the east and west have one side they dont need to defend as much. Judging from the screenshot we are in North and knowing GOTM we are probably in the middle (orange dot) surrounded by three opponents (Red, Cyan and Yellow). And if they expand fast enough we could be bordering 5 civs (purple and green as well) sounds like early warfare.
