Shadow:
Very Rare
Very Large - Very Massive
Mining: NONE
Research:Very Rich - 7x Mega Rich
Artifact: NONE

Shadow planets would be like Gas planets only much much darker in color, they are like Super Research planets.


Sky:
Rare
Small - Massive
Mining: NONE
Research: Very Abundant - 1x Mega Rich
Artifact: NONE

Planets that seem like only endless sky, its kind of a lame/impossible idea, but it would be interesting to see.


Eden:
Legendary (or better)
Colossal - Mega Colossal
Mining: 15x Mega Rich - 50x Mega Rich
Research: 7x Mega Rich - 50x Mega Rich
Artifact: 10x Mega Rich - 50x Mega Rich

A golden planet with colorful clouds and crystals on its surface, some say it is one of the first planets formed in the creation of the universe. These planets are very VERY hard to find and rival even the Dysons!

If I come up with any more I'll be sure to post em here.

For that last one I would make the artifacts up higher too. Because if they are among the first then some very old races may of been then as well increasing artifacts.

True, very true, since it is one of the oldest types satellites and other ships could have crashed on there too.

Upgraded to 10x Mega Rich minimal artifact. I hope Dan likes the idea.

I would call it an Eden planet.

Not a bad idea. XD A lot more easier, but Eden sounds like a Terra-like planet's name, like Gaia. But I see where you get the idea from. I'll change it's name to that, since it is easier to remember and makes more sense.

Disc: (cannot believe I never thought to suggest this one yet)
Mythical
Small - Very Large
Mining: Extremely Sparce - Average
Research: Mega Rich x10-18
Artifact: Rich - Mega Rich x16

A flat disc of earth around which a miniature star orbits.

Halo World(if you dont know where I got the name you are NOT a sci-fi fan):
A extremely large Niven Ring that circles around a star and creates massive amount of energy to power the rotation, terraforming devices, and homes on the ring. Cannot be created by an average race because of the resources required, so are VERY rare.
Legendary
Attributes: Ring Ray or for a more sci-fi name, Niven Energy Allocation Beam: Adds 300 passive attack
Size: Collosal to Mega Collosal
Resources:
Mining: Very Rich-50x Mega Rich(The entire thing is made of metal and has thousands of mineral replicators on it, so i would think you could get a lot of minerals)
Artifact: 10x Mega Rich-50x Mega Rich(The civilization who built it was OBVIOUSLY incredibly advanced)
Research: 5x Mega Rich-50x mega Rich(With this example you could create your OWN Halo )

Shkadov World
A planet created by a very advanced civilization able to move entire solar systems if desired
Legendary
Atributes: Shkadov Thrusters: 300 Passive Defense
Resources:
Mining: Very Rich-50x Mega Rich(Same reason as above)
Artifacts: Mega Rich-50x mega Rich(This would be more like a Defense for a solar system as it can easily evade attack from enemies or natural space disasters, so they wouldnt leave as much on here)
Research: 20x Mega Rich-50x mega Rich(Obvious, this thing has the technology to move a whole SOLAR SYSTEM)

I like how these two balance each other out in a way, but I think the 'Halo' idea is a bit unoriginal, even though it would be cool to own a giant halo in space, I think that Dan makes great strides to make this game as original as possible. However I totally support a planet with the same specs as your Halo idea and your Shkadov planet too.

I have an idea for this topic but taking a totally different direction, space stations. They can be found buy scanning for planets just like you normally do and will come in two types, factory or lab (maybe even rare ones with both). Factory having only artifact production and lab only research. Both can have high production rich or higher but the down side will be limited space about the size of a very small planet or less.

You apparently don't know what a Dyson Sphere is. A Dyson Sphere is a structure built outside of the farthest planet orbiting a star, completely surrounding the solar system (the star and all the planets orbiting it). This structure is able to harness the entire output of the star's energy and has the surface area of thousands of planets. I have not seen one myself yet but I have bin told that they are already in the game

I can't believe I missed this (posted september 16!). Terry Pratchett fan I presume?

NPC planets for all the relevant different NPC races/factions.

If you invade it you get a special planetary building or knowledge about one.

Or you could trade with the faction for knowledge and/or special modules.

I know what that and MORE is. I know more than probably you do about sci-fi mega structures. I know what a Dyson is. And i got Skadov off of wikipedia(Search for it). And the Halo world is different because it is able to create many different enviroments across its surface, and it is a ring, so it has a smaller surfacxe area than a sphere. And i am not a noob. I have seen an image of a dyson and have known about them since MAY when I joined(Check my join date). Ask me if you want to learn more mega structures.

I did not say you were a noob, and I meant no disrespect. I simply assumed you didn't know what it was since the stats you listed for it were more vast then the stats for the Dyson Sphere if I remember correctly. Also I would recommend in my opinion adding to your description of a Skadov that it would have a limited time in a persons list of scanned planets for you to colonize it since it would move out of range rapidly if you don't take immediate measures. That would greatly reduce the chance of someone being successful in taking it from you before they lose the opportunity

If the game developers do decide to make this world I would recommend that they discus it more in depth with Robert since he does seam to have a good grasp of the concept

Relay Node:

A planet sized structure built by a far reaching and advanced society. The structure is designed to store vast quantity's of information and share it between other nodes and let the information be accessed by plants and ships.

The structure would produce a very large amount of research, moderate to no artifact, and no mining, as well as increase your maximum research capacity

In addition if you have multiple Relay Nodes it increases the stats of all the ones you have because you would be able to link them together increasing overall efficiency.

The reason for the structure not being in the control of the original creator's could be that sum anomaly or malfunction thousands of years ago disrupted the link between Nodes and the original race had moved too far out of rang to bother coming back to reconnect the link.

sorry, ihave been getting angry very essily lstely. i am oryy for the orrible grsmmer, i am at a relative's house and hey have a chid who s learning how to type, and their keybosrd has been acting up latey so iam force to use the chlds keyboad. it has a horrible response time and itis hard to orrect mistakes because of the wayi works. theway you stated it sounded to me like you thought i was a noob. I guess i misunerstood

I like this, how about instead of them being high bonus to research planets, why not make them a planet with VERY POOR stats that grants a multiplier to all research points received.

If the planets are rare I would say a 8% bonus per node. (2 planet spots to get a +16% bonus to research).
If the planets are more common then perhaps a slightly smaller bonus 5% (3 planets to get a 15% bonus).

Since they take up planet slots you woudl be a fool to get only these, planet slots are valuable, but adding the occasional node would be a boon. High level and low-levels players a like may want to use these more than mid-level, since low level players tend to settle less useful planets and multipliers are the only way tthey can boost them, and high level players have a death of producing planets so multipliers will have a larger effect for them. Mid-level players however are the ones focused on trying to get a hold of juicy producing planets, and woudl be less liekly to take up a valueable slot with a booster as often as a high or low level player.

I also like the 'Node' idea.

new type sentient mega rich research rich artifact mega rich mineral production. good defense and attack. bad thing if you put more than a third of your buildings to mining the planet will get upset with u and attack you until you drop some mining buildings. if after 3 days of not removing excess mining buildings planet boots itself from your control and fluxes itself.

micro star planet.

Like a gas giant however, unlike a gas giant, the star/planet have just reached critical mass in order to create nuclear fusion.
I'm not sure what it resources are, though it won't have artefacts.
The micro star size is only mega colossus only.
or even bigger!
