What Structures should I build on a 17x Mega Rich Colossal Plasma planet? I'm working on making it, it will be a VM 12x MR Gas tomorrow (using Kronyn abilities). I need 16 more processing cores, which I'll probably have to wait on afterwards.

So far, I want to build:
3 Matrioshka Brains (17 space, 10 res EACH)
1 Sha'din Grid Network (1 space, 2 res)
2 Barrier Nexuses (1 space, 1 arti, 300 defense, +20% def EACH)
1 Adumbrate Station (1 space, 1 arti, 1 res, 200 cloak)
1 Temple of Reflection (1 space, 3 res, +30% def)
2 Domain Walkers (1 space, 600 attack, 600 def EACH)
1 Ergosphere Filter (1 space, 150 cloak, +20% cloak)
1 DM79 Datacenter (1 space, 6 research)
2 Chron Shifters (1 space, 300 cloak EACH)
1 Hypergate (1 space, 2 research, 2 artifact, 2 mining)- it will take some time to upgrade this
4 Obviation Barriers (2 space, 1200 def EACH)

Also has 200 passive cloak

The stats would be (BEFORE legion bonus):
12,335 defense
1,200 attack
1,380 Cloak

44 Research*625% bonus*100% development bonus=638 research/hr

If I'm correct, that's 71 spaces so far. That leaves 4 spaces open for other artifacts. What should I build?

With those spaces, I might build:
Intraphasic Hoveroid, once I get one (1 space, +5% production)
Isolation Bureau, once I get one- I'm the only scanner (2 space, 2 res, 2 arti, 2 mining, 400 cloak)
Resonance Inhibitor (1 space, 250 cloak, 500 invasion defense)

That would make the planet (before legion bonuses)
12,335 defense+500 invasion defense
1,200 attack
2,160 cloak

44 research*625% bonus*100% development bonus*5% intraphasic hoveroid bonus=670 research/hr


Please make suggestions! Thanks!

Akulan gas ingestor, interrogation stronghold, Silthion Gas Vesicle, modified grid pylon, bioship gene lab

How much space per structure?

1 each, positive on all of them except for the akulan ingestor.

Yes Akulan Ingester 1 space but if you had 4 space left that is 5 space

Given his mention of a Sha'din Grid Network, Interrogation Strongholds and Silthion Gas Vesicles may be a problem for him to get. I don't know his rank, of course, so he may be in the 200-250 range where Xavox and Hives are visible but not Hypergrids. On the other hand, there is always stealing someone else's...

Oh Hypergrids , we've had about ten in this week.

Yes the Akulan is 1 space, and I was just throwing out the artis that I could remember.
