I'm wondering if it would be better to upgrade my last +12 building to a +24... or if there are artis out there that will give more production for the 18 space.

Also.. can you use an extractor on the buildings after they've been enhanced?

+24's give a 1.33 resource/space ratio. There's a limited number of artifacts that could possibly fill that amount of space AND give better production. And no, they can not be extracted as they are not an artifact structure.

thanks darth. Wasn't sure if they changed 'status' upon being enhanced or not.
so it would be much much easier for the +24.. rather then wait and hope and pray and do a few months of missions for the other artis?

That's what I did with my dyson. Yeah, it doesn't churn out what it possibly could, but it works for my needs.

Mining 28x Mega Rich 315 units/hr
Artifact 28x Mega Rich 2439.36 units/hr
Research 28x Mega Rich 637.56 units/hr


3 +24's makes most of arti output out of it

and some multipoduction artis (1 spot multiple production points)
sill needs some extraction and arti shuffling, i guess its possible to squeeze out almost 3k arti/h from it

and im holding mine because i dont want to use them and have dan turn around with a another tech Tier about a week later...

So... You're going to miss out on all those resource points on the off-chance that Dan is going to add something for the top what.. 3% who have everything researched already? Pure brilliance.

What I did is upgraded 2 of my 3 +12's to +24's so if I get some better things I still have room to rework it.

As of NOW, any and all very massive or bigger planet (include VL/massive with moons etc) can fit in at least one +24 while having all the better production/space artifacts.
If that is, they need not be defended(that is to say, mission planets)
otherwise, u will need colossal+ or VM with moons etc. But then again, usually non-mission planet don't have all 3 production types "up there" so~ u probably won't want all the following

Specifically, the buildings that give better than or at 1.33:
size 1, Phase Cutter - Tri-Phase Upgrade - Mining: 3
size 1, Phase Cutter - Tri-Phase Upgrade - Mining: 3
size 1, Warp Gate - Mining: 1, Research: 1, Artifact: 1 (or better, hypergate, 2 all)
size 1, Processing Core - Mining: 1, Artifact: 1
size 1, Interrogation Center - Research: 2
size 1, Silthion Gas Vesicle - Research: 2
size 1, Sha'din Grid Network - Research: 2
size 2, HyperSensor Satellite - Research: 2, Artifact: 2
size 1, DM79 Datacenter - Research: 6
size 2, Isolation Bureau - Mining: 2, Artifact: 2, Research: 2
size 1, Adumbrate Station - Research: 1, Artifact: 1
size 1, Adumbrate Station - Research: 1, Artifact: 1
size 1, Refining Lab - Mining: 1, Research: 1 (or better, upgrade, 2x2)
size 1, Relay Tower - Research: 1, Artifact: 1 (or better, upgrade, 2x2)
size 1, Spy Uplink - Sha'jha Uplink Upgrade - Research:2
size 1, Spy Uplink - Sha'jha Uplink Upgrade - Research:2
size 1, Extracted Lithovoric Stem - Bonus Mining: 10%
size 1, Xecti Signal Repeater - Bonus Research: 10%
size 1,* Intraphasic Hoveroid - Bonus Production: 5%
size 1, Zolazin Analyzer - Research: 1, Artifact: 1
size 1, Zolazin Analyzer - Research: 1, Artifact: 1
size 1, Adaptive Spire - Mining: 1, Research: 1, Artifact: 1
size 1, Adaptive Spire - Mining: 1, Research: 1, Artifact: 1
size 1, XTS-10 Injector - Mining: 3
size 1, Meta-Tuned Jammer - Research: 4
size 1, Antimatter Drill - Mining: 1, Artifact: 1
size 2, Sulcation Portal - Mining: 2
size 5, Omnibase - Min: 3, Res: 3, Arti: 3
size 2, Captured T.O. Harvester - Mining: 2, Artifact: 1(NPC Drop)
size 1,* Auric Lepus Drone - Artifact: 2(NPC Drop)
size 2, Bane Generator - Mining: 3, Artifact: 2 (GP)
size 2,* Scruuge Hoarding Vault - Artifact: 3 (Gp)
size 2,* Scruuge Hoarding Vault - Artifact: 3 (Gp)
size 2,* T.O. Harvest Vault - Mining: 3 (Gp)
size 2,* T.O. Harvest Vault - Mining: 3 (Gp)
size 2, Assimilation Locus - Mining: 2(4)
size 1, Permafrost Sub-Network - Res: 1 (all x2 on icy) (Mission Reward)
size 1, Mylarai Stripcore Mine Mining:4, Artifact: -2
size 3, Sillixx Starport - Artifact:2, Mining:2

Note that only the first 14 space worth are unlimited AND aviliable indefintely. The others might have limited aviliablity and/or other conditions.
The total amount of space of those are 52-55(depend on wether u count the 1.33 building), but it's unlikely for them to all exist on the same planet(possible, but meh~), it's probably more realistic to say ~40 space worth on most planets.(-omni, - some of the GP/limited time stuff)

Further more, the next best thing is this:
size 5, Captured Crimson Base - Min: 2, Res: 2, Arti: 2, Att:250, Def:250
And everything after that is 1 production/space ratio
And actully, even if u still have some >1.33 stuff left to place, it's possible that +24 is ultimately better. Specifically:
if u have 4 of the 1.5s(3 production 2 space) left to place still
4 1.5s: +12, 8 space
sillix port +4, 3 spaces
CCB: +6, 5 spaces
OTHERS: +2, 2 spaces
total: +24, 18 spaces
In other words, if u have less than 4 1.5s, then it is better to have a +24

In conclusion, ur mission planets should house at least 1 +24, and it would take ALOT of newly released artis to change that fact. as for the rest, check the list and think on it
