I don't want to "cheat", what I want is an idea of what is out there. I like playing maps with low habitable planets. It drives me crazy that a stars close to me have zero information until I fly to it. So really what I am suggesting is.
Based on sensors (or some other tech) stars in the FOG should have certain information
1) Star Type/Color
2) Based on range from my colonies at least, I should have an idea of planets that are greater than "X" size.
Why would I bother flying to a black hole early in the game?
Certain stars should yield certain numbers and types of planets. A red giant would probably have less planets because it already engulfed them, a white or brown dwarf would likely have no or a couple of poor planets, etc.
So while I wouldn't have perfect information, I could at least get an idea of what is over there before sending a spaceship. I really doubt any nation would send a very expensive ship to each and every star no matter what hoping for a good rng roll.
That said, this game isn't really science based as much as fantasy based, so I am probably over thinking it all.
