Planet Underdevelopment
Newbie here! Been playing about a week -- I win some, I lose some, but always when I check the stats at the end of the game, I'm waaayyy higher in the "income lost to planet underdevelopment" category. But the thing is, i think i AM developing my planets. I forget what the button says, but it's the one in the top left (right below it is the logistics slot improvement button); I usually max that one out within ten minutes of colonizing the planet. And I max out the planet density tech...
What am I missing? Refineries maybe? I often don't get around to refineries until way late in the game.
Thanks for thinking!
