So the suggestion is to try and decouple the res bonus from position to planet values(size, temp) instead.
Deuterium has always been tied to temperature and thats fine and makes a fine line that the higher position the lower the temp.
But what if crystal bonus was tied to planet fields, simply that the bigger the planet the bigger the goldilocks zone where crystals can form
Unfortunately there isnt really a third number for metal, unless you use diameter or position.
But it would incentivize new players to select larger planets than they would otherwise, and prevent a bit of that long term regret some have of keeping a too small planet.
the bonus production procentage range can stay the same. the 35% extra crystal or metal
