This scenario is awesome. You made a real good job with Arbitrary Guy's EE3 Mod.
I started a scenario with Ferdinand III of Castille-Leon in Noble Difficulty and Marathon speed. Like you id52, i built catapults (in all my cities) to attack Lisboa, Porto and Grenada. During this time, Louis XIV asked me to help him in his war against Henry VIII. I accepted but my war with Heny VIII was only naval because my army was besieging barbar's cities or defending mine. When i captured the 3 cities, i put my army around Zaragossa and Valencia and stopped my war with Henry VIII. My naval's victory over him was total but he didn't lose any city.
Then i declared war to Jaime to have all spain and asked Louis XIV to do the same thing (he accepted with no condition). I captured quickly Zaragoza, Valencia, Barcelona and Palma and Louis XIV captured Montpellier. Then I stopped the war with Jaime.
I decided to have control of the seas so i built gallion and caravelle. During this time, i found The New World's Technology and started to buildt Conquest Aztec in Lisboa (120 turns) and Colony Cuba in Bilbao (108turns).
But then i had my problem. There were only 100 turns left for the Time victory. The scenario ended in 1560!!
So i decided to search the shortest technologies, let my population grow and declared war to Henry VIII once again. His presence in Bordeaux and Brest was not good for me and i wanted to give this cities back to France. With the help of Louis XIV, the victory was quick (and with the help of my navy, i controlled and destroyed all the english's supllies) and i gave the cities to France. At this time, i was peaceful: i controlled seas and ennemies had to pass through France to attack me.
I was first, Barbarossa second and Louis XIV third. In the 10 last turns, Barbarossa decided to declare war to Louis XIV. I had army on French territory and Louis XIV asked me for help. At the end, in 1560, France had lost no city but Barbarossa lost Marseille, and Metz was besiege.
I finished first with 1048pts, France second with 998pts (Thanks Ferdinand III), and Barbarossa third with 920pts.
For my problem, i started a new scenario in epic speed and the Time victory is in 1740 after only 180turns (like in Marathon), in normal speed, the end is in 1920 (180turns) and in rapide speed, it is in 2280 (180 turns).
Does someone know why i have this problem?
And one more thing : I love this game!
