This is quite minor, but when DE came out and we were all the sudden able to queue technologies, it was quite consequential, even at high level. A great change! But…
Chances are that late game, one may want to research stacking technologies to make a tech switch. Let’s say I want to swtich into Hussar, and have no cavalry tech whatsoever. I can queue Bloodlines and Light Cavalry, as well as, in the Blacksmith, Scale Barding Armour… But I can NOT queue Chain Barding Armour, nor Hussar quite yet. Admittedly, if I am focused on the switch, I’ll minimise time upon clicking these latter techs after their “parent techs” were researched… but it’d be better to be able to queue it all if I desire.
So there are two solutions:
- Allow to research the daughter tech (say Hussar, before Light Cavalry is researched) in teh same building, queued after the parent tech.
- Allow to research the daughter tech in another building, and if the development should start before that of the parent tech, just make it wait.
