After a break of about 4-6 months from playing the game, I've started up again. However, this time around, I've set myself up with the goal of making my space program professional (because why not). The last few times that I played, every mission was met with a custom build. Now there's nothing wrong with that, but this time, I wanted something resembling a real life space program, with a family of different SLS which are re-used depending on the payload.
Clearly Squad has done a good job of allowing you to do both options, but here I'm just wondering what the proportion of users are like. To answer this question, I've set up a little survey. Not sure how popular this will be, but here goes anyways.
