forget about everything, forget about what this is a game and what this game have a goals.. you - WARCHIEF of this tribe.

Yes your tribe should must pass the 'test of time', but you should not be overhelmed of some sort of things like: "i should focus on this tech tree branch because it's fastest path to UN or space ship". No!

Solve problems as they occur, every turn you got some priceless information, your scouts find 'stone' and you can focus on building Pyramids, or your rival still not find iron and he maybe a good target to invasion etc. Look at this game not like long path to success, look on it how on little steps to success.

Example from IRL, when Arsene Wenger, football manager come to Japan, to train Nagoya FC, club president sayd him: "We expect what our club will dominate in Japan in the next 70(!) years". When you heard this, you understand: 'I'm a small part of a huge, ambitious plan, and i'm not forever here. Then let's do as much good deeds as we can".
