The current size is about 3 times larger than a normal sins planet, so the sun inside is very small (mabe artifical ). The size may change if I tested it ingame.

Population will be high maybe like on terran planets.

Structures health will be very high, cause the colonizable side is inside, and so the siege ships have to do a lot of work

All other stats are still undetermined. Maybe someone has an idea?

I will give it a special ability if I have a good idea.

To make it colonizable it has to be a "planet entity" which means there is also a normal star in the system. Also there will be a special colonize research needed.

yeah, i was thinking about using the TEC starbase texture as a base for the outer shell.

Hmm....  If it is three times the size of a regular planet, shouldn't the population be larger too?  That could lead to some pretty hefty tax income if it had, say, twice the population of a terran planet and was made the capitol though.  Maybe make it so it can't be the capitol, but keep the population high?

I aggree with this.  I don't think it'll need any more logisitics slots than an ice or volcanic planet.  Will you still be able to put 4 star bases in the grav well with the Dyson Sphere?  If not, then I think there should be a few extra tactical slots,maybe 8-12, because it is a much larger grav well to defend.  If it will still take the four SB, though, with the regular planet tactial slots, it would be very very hard to take.  Worth the effort though, I think.

Maybe some sort of culture bonus, because it's such a big project, and its completion is a source of major national pride for the race that builds it.  Or maybe because of the larger population ship build time is increased by 75%, or something.  Of course, the ship build speed might not matter too much, because by the time you've made it to the sun and colonized it, I usually have a large fleet by then anyway.  Hmm.... must think on this more.

Why not make it so that capitals are unable to bombard?  Maybe only fighters and small frigates (siege frigates only?) are small enough to navigate inside of the dyson sphere in order to take out the population so it can be recolonized?  This may not be feasible due to game engine constraints, but would be much more realistic.

Can the TEC shield be used by a planet and not just structures?  If so, you could give it the shield with a good amount of mitigation to reflect how hard is to damage the inside.  It would also go along with the fact that it takes time to damage something so massive.

Also, what about an ability that reflects the fact that it is collecting a massive amount of energy from the sun it is built around?  This could be reflected in massive AM regeneration for all firendly ships/structures around it, a significant boost to its tax income(or trade income from having the ability to make massive amounts of trade goods).

I can see two different types, one designed to support people and thus having a massive population.  The other would be for the sole purpose of gathering energy from the star and could have a massive boost to things like trade income and/or ship/structure production speed(maybe a reduction in costs of ships/structures built there ).

I think it would probably be a level 7/8 research, maybe a base research to colonize and then research to imporve the ability you decide to give it.  The population could be low initially, but have a tech to provide a significant increase with several levels(start out with ice population levels then have the research provide a 200%+ plus boost with at least three levels).

Maybe a good way to balance something that could be a tremendous cash cow would be to deny it any offensive or defensive abilities.  A good argument can be made for having a buffed media center upgrade and buffed trade port upgrade as part of its own developement, but then the sphere has tied up all of the logistic and tactical slots available in the gravity.  This is a huge creation after all.

Perhaps that one special ability, I know I just said no defense/offense abilities, could be disrupting the phase lanes in/out for hostiles.  That shouldn't be too unbalancing since the sphere can't hurt the hostiles, and if you're not on top of your defensive fleet the ability doesn't actually do you any good.

**Edit**

I do agree that this thing should have base hull points of a huge number.  I don't think 16k would be too high to start with, maybe upgradable to 30k or something.  That gives anyone time to get their fleet there if they've been paying attention at all. It'll take a long time to build, it should take a long time to nuke.  Having said that, it should probably be damagable by antiorbital and siege weaponry, since it's a bit of both.

*Shock* *Amazement* After all this time! A Dyson Sphere!

Samurye.

I only play TEC, so....  The second tier ice planet colonization is a level 4 research.  Why not make the research for these spheres a level 6 in the same category as the rest of the planet research?  Or you could put it at a level 3 research, in the same category, and increase the cost, like you were saying.

Okay, two starbases sounds like a good balance.  It makes sense now that I understand that it's not the main star, lol.  Will the sphere have the usual tactical slots, or just the SB's?

I like the idea of being able to upgrade the spheres like star bases.  They can be upgraded totaly to a military purpose, or cut a few of those abilities and be strong in trade or repair or something else. 

I am not sure what the best way is, cause both the "dyson sphere" and "the Citadel" are very special planets and I will use them only in special scenario maps. Which means I won't add them to any random planet list in the galaxydef.

Maybe a few but not that many as a normal planet, cause of the increased health.

Unfortunately the Sphere is not upgradeable like a starbase, it is still a planet and I was talking about the planetary upgrade, like population, tactical, civilian, infrastucture....

But the costs for upgrading can be set for each planet in its entity file, so i am able to increase them.

yes, i'll make one or maybe more by myself. but everyone who downloads the mod can make own maps with the Galaxy Forge Tool.
