I decided to do what (to my knowledge) no one has yet done: instead of making a single mission, making a mission pack. The theme: Interning at the KSC. This mission pack features an intern as the main character. Start with some basic tasks, then work your way up to managing the entire space program.
This is not released yet, and will likely take a significant time before it is, but I will show you the progress I've made so far:
The only completed mission as of yet is Ore Gathering, in which the player must pilot a rover already on Duna and gather 75 units of ore before 10 hours is up. Again, pretty simple to start.
I have another mission in the works, but I will reveal that when the time comes to do so...
