"Economic-wise, that building can easily replace all your T4 (or T7 for later chapters) production, as it gives you more goods per spire than a factory per week (when feeded)."
perhaps im missing something then. Because the main goods per 24h and the goods from the feeding effect both say boosted t1.
Granted, with the feeding effect active, it could likely out produces t1 factories. (Depending on how many t1's you run, and if you keep them level capped or below AND how much spire you can do.)
Just as an example; i have 5 steel factories going now. Not fully level capped yet since i used my pop/cult for military, but close. In theory (not gonna happen) if i ran all 5 at 3h productions per day, i would yield 57,960 steel. (5factories *1449 goods/3h =7245 goods/3h * 8 rounds/day=57,960 goods per day *7 days = 405,720 goods per week (again, not gonna happen, its just in theory. Im not doing 3h around the clock.) (And thats without MM or other effects like storm phoenix)
Using chap 9 for reference on Gildo: 4400 goods/day * 7days= 30,800 good/week. That would leave 374,920 goods left to tie. At 9420 per chest (feeding effect) i would need 40 chests to tie. And there is a total of 48 encounters in spire. (not sure if bonus chests count with feeding effect)
So yea, Gildo would produce more t1 goods per week then my t1 factories IF i kept him fed AND did the full spire. Counting in the fact that actual t1 production would be lower since im not doing 3h around the clock. Yes, gildo would come out a little higher.
Also worth noting that relic boost and AW boost (for t1 goods) would come in to play for t1 productions as well. And everyones might be different; another reason im just using my own numbers as an example.
So
IF i were to do the full spire then gildo t1 goods would come out ahead. Another benefit would be it takes up less room then my 5 factories. (might be the best part of it).
On the other side, it takes 1-2 petfoods every week. Which considering the amount of evo buildings with a feeding effect, might be hard for some ppl. Also the reduction of catalysts in the spire will make the ability to craft petfoods all the harder. So in time, those could become a lot more rare as well. - And more importantly, requires the ability to do the full spire every week. And with the recent changes to the spire and the reduction of time instants... i will no longer be able to do. (so sad... so horrible...).
One other point to consider... in the end, we are still talking about t1 goods. Even if the stars aligned and gildo would yield me more t1 goods... i dont need more t1 goods. Maybe that will change in later chapters, i dont know. But right now they wouldnt be of much value. At best they would go to the cauldron. At worst, just make my stock pile bigger. So the benefit still seems limited to me. Again, maybe there will be more use for them n later chapters that makes it more relevant, i dont know.
So the real 'benefit' that i see would simply be the space reduction. A 3x3 evo building is certainly a lot less room then 5 5x3 factories. (9vs 75). But it still require the ability to feed and do all spire.
One last thing to consider is the 'gain x goods' quests that show up each event. Now and then inno seems to like to through some in that only count t1 goods instead of t1,2,3. If you had already finished the spire then you cant get any more t1 goods from gildo bonus. If you replaced t1 factories with gildo then the only option you have is waiting on his 24h cycle. But at my chapter, its 4400 a day. Usually those quests are 50-60k t1 goods. thats 12-14 days without missing a day to get that many goods form just that. (Again, dependent on each player. Some might have other evo buildings of sets that give t1 goods). But that could be a problem. Might have to leave a few of those t1s out after all. Of course if you do that, then you gaining space benefit is decreased...
So a lot of player/city dependent stuff in there. But over all i dont see the big draw in the design of these stats.
Last thing ill note is that this all made sense in my head as i typed it up. But my head is kinda spinning al little from unrelated issues. So im hoping i just got something wrong or missed something. Its not like im hoping for a bad evo building. Id rather it be good, of course.
