It's not surprising, but it never fails to amaze me that people hear about projects the first time, that have been around for decades. (This is not an attack). The first time I hear about MAME was maybe in 2004 or so. At that point the project was already over 6 years old. So for me that project is ancient, but when I heard about it the first time, someone was probably also amazed how I could not have heard about it earlier.
