OK, I've had a chance to look it over more carefully. Really looks good. A few comments.
- I really like how Venus looks. I've seen elsewhere that the volcanos might be turning plots into Earth plots, so maybe we need some exovolcano features.
- The Sun looks neat too. I noticed the plots on the far East column are all Sun, while the adjacent plots are Sun-Like Star. It might be better to convert then all to Sun so that we can build a Sun Scoop and other such things.
- We need a Cislunar Space corridor through the moon, since otherwise there is no way to get a Planetary Settler to Mars. I don't think that similar corridors for other planets are needed, but they might be a good idea.
- There's a lot of Titan (Methane Moon). I would like to expand the Titan material and have about the same amount as on Venus, and decouple the Titan line from the Solar System line. But that would be a lot of work and a ways down on my list.
- Is there any Neptune (Cold Ice Giant)?
- Yes, I know the names are not very intuitive. There is a Very Cold Moon, which is basically Triton, that goes with Neptune, and the Cold Moon, which is basically Umbriel, which goes with Uranus. Of course, there is no law that says that all solar systems have to look like ours, so they can be mixed and matched. But I hope the names aren't too confusing.
- The Planetary Ring was meant to be the rings of Saturn. It won't do any good in Interstellar space.
- A few more Oort Cloud features would be nice.
- Could you add some more Orion Arm? That's where most of the action is going on in the second half of the Galactic Era. Maybe we don't need so much Star Cluster.
- I noticed the seam between Distant Past and Distant Future. That's my fault for giving them the same layer order. I'll fix that.
- I didn't plan on having Hyperspace, Distant Past, and Distant Future appear on the map natively; they are meant as synthetic terrains that are created by some units. But the seams of Hyperspace that you added are really cool. In general, it's really nice to see how you've developed the map in a way that I didn't foresee.
I haven't actually played a game yet and unfortunately it will be a long time before I have time to do so, so I can't comment on what the map is actually like in gameplay and there might be issues I overlooked. But it sure looks fun.
