It would be good if SAR had more longer-term goals for players to work towards built into the game. This would be e.g. something an average player can work towards in the span of 2 months. This would provide the sense of reliability and stability that you are constantly working towards a goal, and the satisfaction from eventually reaching it, increasing the chances that players will come back repeatedly to accomplish the goal (replayability).
I think this would help some people that need affirmation from the game to help them find fun in the game.
Discuss what long term goals are possible as well as the idea of long term goals below.
