So we'll jump from the Stoneage right into the Iron Age.
Dont like it how they discard a resource like Copper with its major role in History so easily.
civ4 extrapolated the assumption all civs would have access to tin and would smelt their bronze... Why can't civ5 run on the assumption that all civs have access to bronze
and tin?
Spearmen (which are powerful and useful in civ5) come at bronze working and don't require a strategic resource from the map. Surely we can run on the assumption that bronze is simply far too common and just about every ancient army was able to supply their troops with it.
Spears are the new axe: They come at Bronze working, don't require iron, are stronger than warriors (by a mere 1 str, but still...) and are probably cheaper than swords too... In addition, unlike civ4 axes, they don't need to worry about mounted units. Honestly, I'm foreseeing the "axe rush" becoming a "spear rush".
Also, no; we don't go strait to iron ~ since we can only build as many swordsman as the Iron we have in our empire... Which means a decent portion of our ancient army may still be comprised of Spears (in addition to horses, archers, and catapults as you discover all of the military techs).
civ5 is about combined arms, and actually necessitates it, by the looks of things... Spamming 1 unit (the axe) isn't an interesting gameplay style. Regardless if anyone here did it; the axe due to it's advantages was easily the most versatile ancient unit and could be deployed to great effect by having an army almost entirely of them.
