This is an absurdly careless attitude to have. We do not want to play around with this and discover the full extent of how bad things can get.
We know EXACTLY how bad things get:
-Tech 0 - Nothing.
-Tech -1 - Lose the passive innovation roll for 1 turn while it refills.
-Tech -2 - Lose the passive innovation roll for 2 turn while it refills.
-Tech -3 - Risk of losing unsupported technologies
That's standard for our actions here.
Additionally, there are no known ways to randomly lose Art, and thus, no known ways to randomly lose Tech.
Ergo, the only reason for Tech to hit negative and stay negative is if we deemed an opportunity more valuable than 2 turns of passive innovation rolls.
There is no urgency to rush Tech points when our ass is on fire.
You're thinking too small and you're being unfairly selective in your thinking. Every annex starts giving non-linear things after a certain level has been reached. Level 2 library holds all usable information, yes, but that doesn't mean higher levels are useless. Higher levels will give us additional things beyond mere record space and it's wrong to not recognise or acknowledge that.
Never said that, I said Arsenal 4 gave better R&D benefits than Library 4
Not that Library 4 is a waste of space.
You have to recall that the Palace is primarily a place of governance
not scholarship. That's what the Temple Libraries are for
Library 1 - Records storage.
Library 2 - Records and reference materials storage
Library 3 - Records, references, and esoterica storage
Library 4 - Records, references, esoterica and trivia storage
Libraries
preserve ideas.
But if you want to
create ideas, you need:
-Research staff - We don't have this. This is behind Shrine 2
-Experimental production - We don't have this. This is behind Arsenal
-Experimental gardens - We don't have this. This is behind higher levels of Garden.
A library is not a magic technology button. It's biggest boon to technological advancement is that it saves a lot of manpower from the process of passing down knowledge and cuts the risk of information loss.
Is there a purpose to the Temple having a library recording every bit of esoteric knowledge like the growth patterns of leaf veins? Yes, absolutely. Priests reference it to come up with ideas and theories, leading to mathematics or biology knowledge advances.
Is there a purpose to the Palace having a library recording the growth patterns of leaf veins? Not nearly as much, the King and other decisionmakers are generally too busy to read or enjoy esoteric trivia. You would need say, a body of expert craftsmen or a large number of in house priests to make use of that.
The Royal library is not intended to be a comprehensive and complete collection of all the People's knowledge, and attempting to do so provides diminishing returns unless paired with similar levels of Shrine and Arsenal to provide enough priests and engineers to make it useful.
So you look at the other Annexes:
-Great Hall 1 - Basic hall for meetings.
-Great Hall 2 - Grand hall for audiences
-Great Hall 3 - Auditoriums or ballrooms for making speeches to the elite.
-Great Hall 4 - Grand courtyard for semi-public events
Great Hall scales fairly well with Royal functions. Generally the bigger the better.
-Shrine 1 - Shrine housing the royal spirit advisor.
-Shrine 2 - A full Royal Temple, which contains additional staff to advise the King on more exotic stuff and conduct rituals under royal auspices. Kings are more likely to have non-zero Mysticism
-Shrine 3 - A temple grander than Great Temples outside(at least, while we hadn't upgraded them). The Palace becomes a religious center in it's own right. On the plus side average Kings will start having passable Mysticism scores.
This is actually not good if you wish to avoid God-King as you go too high.
You can see some of these will hit diminishing returns sooner.
Furthermore, each of the expansions will bias the Royal seat towards different aspects of society by increasing access from those segments to the Royal person, Shrines and libraries to priests, Great Hall to nobles, Arsenal to artisans and warriors, Storehouse to clerks, Gardens to farmers.
Now, given indefinite expansion room, I believe an 'ideal' mid term Palace for the goal of technological advancement is:
-Arsenal 2
-Shrine 2
-Storehouse 2(after Arsenal 1 to house both materials and output)
-Gardens 2(After Shrine 2 to provide greater access to herbs and drugs)
-Library 3(after Shrine 2 and Arsenal 1 to provide the experts to use it rather than a white elephant)
-Great Hall 3(after Shrine and Arsenal 2 to rebalance royal access rather than overly favor the Guilds or Priests)
Though considering it takes 14 slots and we currently have 11, you can see the problem.
@Academia Nut how feasible would it be to demand the Great Pyramid if we win the war? Basically starting a Megaproject to go down and steal the thing stone by stone? They aren't mortared in after all, and thus not "nailed down". And everybody knows you should steal anything not nailed down when looting a defeated enemy.
They don't have the Great Pyramid yet. It's currently a ziggurut I think.
Pyramid is the next step up.
We could, of course, snipe it out from under them.
