Oh, Thank you! I didn't think about that. But it could be solid investments. On other hand when you consistently give tirbute (100,300,800 coins)...and eventually all techs...
I have won recently, but with one reload. In the first try 2 mongolian knigts broken my tanks...and having empty city i gave automobiles for a peace...after that thier demands inreased and they came with tanks...
Next time i didn't build hoovers dam and didn't give tribure so often...and I gave them automobile much later when i build SS.
Also i lost other game, where Zulu demanded techs and i gave...well, eventaully they outtech me near electronics.
So now I decided to refuse their demands from some moment.
Btw, what is a normal date for SS win in such type of games?
Some notes that i did for myself:
1. Don't settle in place, explore the area a liitle bit (up to 3500bc)
2. Then bronze working and Colossus (oftently AI didn't build it before 2500-3000bc). If Coloss is lost - better to restart.
3. Build (don't hesitate to rushbuy) library, marketplace, temple, and Copernic's Obs (this wonder is also very important).
4. Go for Republic straightforward, and then WLTPD.
5. Try to make most of research berofore 1 AD, when it takes 2-3 turns pesearch, then build some infra and so on.
6. Next important wonder is Newton's college and then Shak's theatre goes. But if AI did build Shak's theatre just go for religion and put slider at 10% for lux. It's acceptable i think. Other wonders are later and they are Darwin, SETI and Apollo.
7. Caravans...well, they are very nice, but it's not possible to build them often. So mainly - for 3 trade routs. And other (when nothing important to build) for wonders and SS.
With this rules and a good settling place I should be in nice position about 1000-1200 AD.
My fisrt win was about 1870AD. But I think it could be better with right build and tech orderings.
Any your hits? Which places should be improved?
