I considered uninstalling after a few plays, but then I decided to try the challenge mode. Challenge mode completely flipped my enjoyment of the game. In addition to giving more of a purpose and direction, it goes through all the game setup combinations (Sponsor/Cmdr/Rules) that you might not try otherwise.
There isn't an intended order of the challenges, but I did it by sol deadline (short to long). Doing it this way is kind of a good tutorial as getting perfect times on shorter missions helps build strategies that help for longer missions. Longer missions being harder to know if you are on track to beating.
What this also means is that once I beat all the challenges, I uninstalled it. If they add many more challenges, I may revisit, but I doubt I will otherwise.
