This is a deck segment unlocking delay file for the human player in the sandbox. I have added my comments in dark red. These comments are based on my own analysis of the code and my experience in working with it. I do not have any special inside information from MuckyFoot about these files, and I may in some instances be wrong.
This file is not used in the sandbox. My guess is that it is not used because there is no way to unlock a segment on just one deck. The evident purpose of the file was to slow down expansion by requiring the player to wait a specified length of turns after opening one segment, before being allowed to open a further segment in that direction. But because the segments unlock on all three decks, the effect of the delay is not very effective. Imagine that you are opening all of the Tech Deck, and you must wait for the required amount of time between opening bulkheads. Well and good, you have done so and the delay appears to have served some purpose. But now you can open both of the other decks completely, without any delay, because the segments have been unlocked on all three decks each time you waited on the lowest deck. The existance of this file suggests to me that if the game had continued development, we might have had a segment unlock function that was deck specific.
