Yeah, I’ve thought on the story mode a bit, and I was actually thinking of a virtual month of missions. Kind of like “Papers Please.” I don’t know the exact duration because I haven’t planned the whole thing; I think I know the ending and the beginning, it’s a question of how much middle to have.
I have never heard of “I’m on Observation Duty” and you’re one of 3 people now to mention it to me, so I think I’m going to have to give that a spin.
