[PvK]

I think in general the ancient race trait has advantages that make sense, but I would prefer that all views of "known but not currently observed" systems to only show the Last known data. Ancient races could be given the data as of before homeworld placement.

On the other hand, it kind of makes sense that ancients would know where the ruins and other races homeworlds would be.

The effect can be reduced by turning off the "homeworlds have the same size" option, but this can lead to advantages for Gas Giant empires.

As for ruins, I definitely think it would be neat (at least optionally) to have ruin location be less immediately visible. I'd like to have to fly by or colonize a planet to detect them. In my Proportions mod I made it so many ruins actually don't provide any technology, which partly helps. Unfortunately I didn't find any way to mod it so that ruins were actually invisible until colonized.

The main reason I rarely use Ancient though is because I think it's a bit less fun not to have to explore.
