Looks like they are mostly gone - I found a single PQ1 in my current immense abundant everything, nothing below PQ4 (except Wisp) in the previous 2 games.

With a habitable planet count of ~530-540, an immense map in TA is a bit underwhelming compared to the 750 in a DA gigantic (or 950+ in earlier versions of DA). I was kind of hoping for 1000+ in TA immense, but no joy   

The PQ1 worlds were quite usefull if you are neutral. They turn into pq16 worlds after you have all the techs. This gave you a great boosts around mid game when no other worlds are left.

Bring them back please

One problem with the PQ1 worlds was that the AI never used them. We still have the odd fact that the low PQ worlds actually update to a higher PQ than home worlds. While we are at it, why do home worlds have such a mediocre PQ? I think home worlds should be PQ26, or whatever is highest at the very least.

PQ should be *gasp* yet another slider, or there should be a way for you to set the range (and average) that PQ can span for habitable planets. (But then, we might not have a game anymore, but just a "collection of options" (or something) as someone from Stardock allegedly put it.)

PQ 26 unlikely to be a home planet.

The environment is so friendly there are few extinctions and less need for intelligence to survive. Hence, intelligent, sentient lifeforms are less likely to develop and/or survive.

I disagree...

They might as well redesign the planets screen to show us much less tiles on surfaces since the extra "emptiness void of lost potentials" locks up our intelligence to an *access denied* loop hole so big i'd rather slap all of my buildings side-by side cross-wording my way to the bottom and the last square on such a small grid as a sufficating 9x5 but with all & each tiles available to me even if un-terraformed.

You can delay High PQs advantages through design rules (and, as a relative concept - their exact opposites) but not a mind focusing on ONE simple intelligent strategic development worth thinking for.

Not far off, why i simply hate the pseudo enhancement potential call lines in the planetdescriptions.xml files, btw or even, why X-HomeWorlds are beyond what a randomize function can enforce to me.

Even so, the rarety of any given factors doesn't make a game less likely to fulfil its main goal - challenging context but instead simply refines it within a proposed limit. Then, so be it. Nothing stops me from PQ digging a few tiles more though from AIs property if that's what it takes.

Thus, a 12x6 grid of tiles seem comfortable to look at if half-filled but certainly doesn't represent Oceanic expansion, Underground tunnels or Atmospheric locations.
