Turn 30:
I check all the tribes and it reveals this:
The Zulu have: Masonry, The Wheel, Warrior Code, Iron Working, Mysticism, Alphabet.
Japan has all of that but Alphabet.
Persia also lacks Alphabet.
Iroquois only lack Mystisicm.
France lacks Alphabet, Mystisicm and Warrior Code.
I make 8 gpt and have some cash. So it's time to trade.
-The Zulu give me Alphabet for 4 gpt and 11 gold
-The Persians give me Warrior Code and Mysticism for Alphabet, 4 gpt and 11 gold
-France gives Masonry and The Wheel for Warrior Code, Mystisicm and 19 gold
-The Iroquois give me Mystisicm for 64 gold
A couple of tribes have Horseback Riding. But not all of them.
-Japan gives Horseback Riding for Alphabet and 63 gold
-France gives Iron Working and 9 gold for Horseback Riding
I now have all techs known to the 5 AI
I put a scientist in the useless city to bring me Writing in 50.
Horses are next to my capital.
Another event is that I now see orange borders: Beam! Worrying is the SoD of the Zulu that nears me now...
