Physical security is so important. I was really surprised when the Xbox team moved from the RedWest campus to Studio A. In RedWest, we had a building that was pretty much all Xbox employees, and other Microsoft employees couldn't just badge in. In Studio A, if I remember correctly, it was all just public access. The consoles are everywhere, and people's offices weren't normally locked (before most people moved into to bullpens, which didn't even have doors). For the most part, you can trust the employees. We had take home consoles that were signed with the proper keys to run retail games, but could also be debugged and get crash logs, and those were fairly safe and well tracked. (You were told, don't let your friends see/play them) But you can't trust anyone else who just randomly enters the building, and with teams so big that you don't know everyone, politely holding the door open for someone is just asking for it.
