Perfection
The Great Head.
So I was playing as the English in a Huge pangea map, (80% water, 16civs, Diety level). I find myself on this meduim sized jungle and desert Island so I think thats odd but I keep playing. Than I build they Great Library. With my galleys I can't find anything so I think okay better stock up for when someone finds me! I built tons of spearmen and managed also to amass huge gold. (I set Science at 10%). Then one day an Egyption Ironclad pulls up to me (I'm currently researching Monarchy) and I buy their map and contact with a civ. Boom! I'm at the Inustrial age! Then I open my capital too see what I should now build and in the upper left hand corner is 16 rubber! All I had to do to defend my entire Island from this great mean ol' world was to stick my spearmen at the side of my entire continent! When they attack they bombard it down to one and just have sit there. Latter due to Heliocopters I had to move Inwards a bit but thats it! I bought factories and built me a spaceship! The lesson is even the lowly spearman has his day!
