Is Test C's best-REX-possible given our Religious Beeline a safe enough option?
Yes, in Dhoomstriker's test c [
Partially build a Warrior -> Worker -> continue working on the Warrior while growing to Size 3 -> complete the Warrior ASAP], he does exactly that. My question is whether or not we want to just go ahead and finish that first warrior before starting the settler, which is my
Test iii: Grow to 2 ASAP, finish warrior -> worker. It puts our two settlers 2 turns behind and we're 3 worker turns behind, but we have 22 extra warrior turns.
With Test C, we still get a 2nd Warrior out relatively early, but as you say, we get it out a bit later than the earliest we possibly can get it, with the gain of an improved empire. I would argue that we still get this Warrior out early enough to still have Barb Animals roaming around, which is a safe time to get it out in my mind.
For a team that seems to want REX as their secondary goal, Test C seems to be most in line with this goal.
So, the most important question is: will we have enough Warriors in order to keep our empire safe?
The answer is to do all of these things and we should have enough Warriors:
a) Keep our initial Warrior nearby, scouting for city locations 2 and 3
b) Use Monotheism, if possible, to expand the borders of a second city, to help reduce the fog of war and to increase the city's defensive level, should we find ourselves needing to whip a unit. Alternatively, we get Judaism in our capitol and its borders can expand to the next level that much quicker, again helping expand the busting of the fog of war.
c) Plan out our fog-busting locations. 1 unit can cover an area of up to 5 x 5 = 25 squares. Realistically, it'll be more like 15-20 squares, depending upon how close we park the Warrior to our cities and how much Coastal overlap there is
d) Try to keep our initial Warrior alive. That means healing him immediately (with the possible exception of first moving him for one turn to within our borders or to a Forest on the Coast after winning a battle, for a better healing location). It also means running from any Bear that appears, so ending his turn each turn instead of Fortifying him will help the UP player watch for this risk. It also means trying to stick to Forests and Hills when scouting, as much as possible, after the first 20 turns or so, when Animals begin to appear
e) Be prepared to delay our 3rd Settler if we lose a Warrior, spending 4 additional turns to build its replacement
Summary
If we keep our Warriors close and if we take good care of them, 3 Warriors (including our initial Warrior) should be able to help us fog-bust. Add in religious border expansion and the chance to be able to whip units before Axemen come out, and we should be laughing.
