There are plenty of games announced every year that never see the light of day. Whether they run into development troubles, can’t find a publisher, or get blown to smithereens in a terrible accident, there are a lot of reasons why a game will fail to ship. Most of the time, it’s with good reason and the world’s no worse for their lack of appearance.

However, every now and then there’s a game or two announced that seem so amazing, so revolutionary that it’s absolutely heart-breaking when their plug is eventually pulled. This is a list for all the times you ever got excited reading a preview article, watched an amazing trailer, or placed a pre-order and never got to play the game you desired.
