There's all sorts of philosophical implications behind immortality. Is it really desirable? Wouldn't you become bored after living for so long? What if everyone lived for that long? This is the focus of The Escapist's latest Game Design Sketchbook, featuring a game about choosing immortality or death. It is appropriately named Immortality.

Move around with the arrow keys, and press down to pick up blocks. Your goal is to place blocks to reach either immortality (the infinity symbol) or death (the skull). You can only scale blocks that have the brown steps sticking out the side. It's a very simple short game, but it gets you thinking. It's free, so download it from The Escapist and give it a try. Just promise us you won't catch a case of Philosophy.
