I have been thinking about that for a while maybe is to complicated to add this to KSP or maybe my mind is drifting too much but i thought that may be great to make in everi start of a carrer a quest line. My english is not good enought so i try to explain me better.
To give a big purpose may be squad can genareate 3 or 4 random quest that habe no contract involved.
for this quest will be nice to land in a concrete place and make a kerbal visit certain location like the monolith we found but random and every of these monoliths can give you a clue about where you can find the next
For exemple you see after scanning ALL Kerbin that 1 of this random Monoliths is in a certan location. You send a Kerbal there then you read about the next monolith planet location so you need to go there use the scaners send back data and then use a kerbal to go there and find the next.
After you find the last maybe some nice historical or cachi phrase in the last will apear and maybe the option to start again the quest.
I hope this dosn't sound strange or boring
