Here's a map that uses Mitchum's latest Test Saved Game.
I played out the game building the Worker immediately after growing to Size 3. The Worker was just completed and has started irrigating the northern Corn.
During this time, Hinduism expanded our borders to what you see in the screenshot.
In this game, I "goofed around" with Warrior 1 and he died to a Lion. Far better would be to keep him in place, ending his turn (by pressing the Spacebar at the end of each turn), which, by the way, gains you the Fortification bonus but has the bonus over Fortifying of centering the screen on the Warrior on each turn, so that you can respond to Barb threats.
Those big 5x5 squares that you see are the areas that a Warrior can fog-bust. The teal 5x5 square represents what our Warrior remaining in place can fog-bust. Along with the Lions and the Bear, by remaining out there, we're doing a great job of preventing new units from spawning.
After Turn 50 is when the "fun" begins. Animals slowly start to disappear from the map. The immediate effect is that the Animals stop fog-busting. If we don't have fog-busters in place, then Barb Archers start appearing.
The lands to the WEST are not going to be fog-busted by any AIs. The lands to the north and east MAY get some fog-busting by roving AI units.
I have placed
PINK SQUARES to indicate "passive fog-busting" performed by our Cultural Borders. It is possible that we may get a couple MORE squares fog-busted, depending upon the currently-hidden terrain, but we should get at a minimum all of the pink squares that I marked.
With just 2 Warriors in the west, we will hardly ever spawn a Barb unit. Without those 2 Warriors in the west, somewhere between 3-4 Barb Archers will appear by turn 60. We will have NO AI units on that side of us to take out those Barb Archers.
Where the Warrior is located now, and possibly in the Plains Forest square to the east of him (which is daring to move to with the Lions roaming around), he can do an acceptable job of fog-busting the area. Preferably, we'll get 2 Warriors out there to do the job properly, as my pink squares indicate.
However, WE NEED to be in that area on or just before Turn 50. Can we honestly justify sending Warrior 1 away and then back again? Can we get him back to there safely past Lions in flatland terrain? It's unlikely. If we have to get him there past Archers, due to having to dodge the Lions, it won't even happen.
So, my recommendation is to keep Warrior 1 out there, partially fog-busting for new Animals, while preparing to eventually go to the FOG BUSTING 1 location.
I have also mapped out my suggestion for moving Warrior 2. I would strongly push to have Warrior 2 come out after the Worker, but just in case I am overruled, I put up a suggested movement path for him now.
Warrior 2 should check out the BLUE SQUARES for a potential Seafood Resource. We need someone to do that before Settler 2 is ready, and I strongly suggest that this "someone" not be Warrior 1, unless you want to whip away our cities, throwing away units against hordes of Barb Archers, possibly throwing away The Oracle or at least killing our economy while doing so.
I didn't map out ALL of the arrows to get to the BLUE SQUARES' area, as it will depend upon what's in the hidden squares as to which direction the Warrior will need to explore down there. Just make sure that whoever sends the Warrior down there, they uncover all of the BLUE SQUARES.
The ORANGE SQUARES will hopefully be revealed for free via a cultural expansion. If not, then we can consider sending our Warrior that went to the BLUE SQUARES to finish off exploring the ORANGE SQUARES as his next task, before going west to fog-bust.
Yes, exploration to the north and east will be ideal, but let's do it safely with a later Warrior 3 (possibly inserted into our build order before Settler 3 is complete), as even 1 Archer appearing to the west can cost us 3-10 Warriors in sacrifice (due to dying and then more Archers spawning due to not having more fog-busters out there, possibly allowing Axes to spawn as a result)--not worth it.
