I don't think developers of any game should be forcing strategies, they should naturally come about given the circumstances of play. Thats the problem i have with overusing tech pairs.

If you win by min 10 then, yes.  You are showing your ignorance in this thread. Again, I suggest you play multiplayer. 

I made a compact  version from the last version I had of unitsAI.js UnitAI~convert.js

The Colossus of Constantine looks impressive.

We are strictly talking about eco techs here. You can skip any tech to get more military, but is that really the best choice in mid to long term? Rushing is also an all-in strategy that basically skips techs. Phasing up fast, yes. Followed by immediately getting those eco techs that you ignored up til now. If you don't get them, you are way behind, no matter that you're in Town phase 1 minute before the enemy. 

RPG games have been heavily dumbed-down ever since Oblivion. In Morrowind, if you played fairly, you had a choice of mostly +2, +3 and +4 (if you were very lucky) attribute points per level up. But, players figured out that, by leveling up your Misc skills that don't contribute to leveling but still count towards attribute bonuses, you can always get +5 bonuses at each level up. So, there was a profound choice: you either role-play and have fun with the game, or you play a boring game with numbers. In Oblivion, you could do the same, but the enemies would get stronger each level up. This prompted players to go a step further, to limit the amount of level ups they do. What does this have to do with our RTS game? Well, if every eco tech is crucial, and every civilization can get every economic tech, what choice do players have? The most logical choice is to get all techs, ASAP. We can't really role-play in this game.  Therefore, pair-techs are one way to make the player take a risk and have consequences for his/her actions. To force players to have a "strategy", if you will.
