Everyone should know what I'm talking about, easter eggs, bonus content and even commentaries. I love seeing these things in a lot of flashes that I watch, but do a lot of NG users also like seeing these sorts of things. I've usually always tried to make bonus content in any project I've worked on, but is it really worth it? It just seems like a lot of Newgrounds user watch the basic part of the flash, then toss it aside, which really kinda sucks.
There are quite a few different styles representing bonus content in flashes, hidden objects, titles in the books on shelves, a bonus content section, or written commentaries throughout the animation. I'm curious if a lot of Newgrounders even care for any of this? or if they do, which is their favourite?
