Similar. Two cases. First was taking charge of the entire Bases secure network upgrade because I was the only one who knew how the new devices worked. I ended up having to attend a meeting with a General and his staff and had to be chaperoned by an E5 because I was only an E3 at the time.
The second was my entire time working in White House Comms. Can't talk much about it but I'm sure you can imagine how out of place it would feel.
You might be interested to know that there are several hardcore modding scenes, where the point is to mod the game for fun. The mod guides are updated every month or so and includes thousands of mods. It takes days to install, and actually playing is optional. In most cases, a new save is required every update, so modders keep an additional playable state if they actually want to play the game.
Lexy's LOTD is my fav one, it's only over a thousand mods, has very detailed instructions, and a very friendly community.
