Starlifter, can you explain your reasoning for wanting to road first?
Sure. Its because we have 2 settlers, the tile is grassland shield (esp. with water access), and the NW and SE sites are excellent locations for the 1st city, given what we know. There is no way we are not going to use this terrain (e.g., we are not going to wander off and not have cities in this area until after Explosives). It costs 1 day of movement to mount a tile, and 2 days to finish the road. We save a settler-day, and have a guaranteed 4-resource tile with trade regardless of the outlying (black) areas.
So in essence, we are getting a "free" move by having Settler#1 on the grassland shield to build the road. It will not cost a day in teh future for a settler to slide out and irrigate it, either (once it is roaded).
And finally, at Raging Hordes, roads are key for defense & leader killing.
Of course, later on, roads increase trade & reduce empire corruption (if the road is the "correct" path, that is).
The alternative to not roading is to move and build immediately, or send Settler #1 out exploring. Both those are pretty much long shots. The former is not sound, due to lack of visible trade tiles. The latter has potential to "pay off", but the odds are against it, esp. when weighed against the loss of production when moving without rivers or roads.
