This PD module reworks habitability to better represent the subtle differences in each planet class in the tradition of "Habitability Reworked" and "PD Reworked". Every planet is given a space on a 6×6 grid.

The system is not equal for every class, but planet groups (wet/dry/cold) are still respected, with each planet gaining a minimum of 50% on those planets. Planets near the center get few bonuses but medium habitability on many planets. As they get closer to the corners, they start gaining more and more habitability for like planets but low habitability on all others, and this will hopefully make an equal game for each planet's choice.
