Given how completely wrong I was about emergence

, I decided to check this one out to see if I'd been using the term wrong - I found this definition over at eeggs.com:
"In the context of software, an Easter Egg is a hidden feature or novelty that the programmers have put in their software. In general, it is any hidden, entertaining thing that a creator hides in their creation only for their own personal reasons. This can be anything from a hidden list of the developers, to hidden commands, to jokes, to funny animations."
I thought the idea of the game's camera actually interacting with the game's geography was entertaining enough, and obscure enough (you could easily go through the entire game without ever noticing it) to count as an easter egg - sure, it's not the killer mice in Max Payne or the Max in Shadows of the Empire, but it's not bad. Of course, the definition might be a little broad, after all, under those terms, Megaman's famous blink could be considered an Easter Egg.
(BTW - I only mentioned it once, the teaser paragraph in the post is always just the first paragraph of the review)
