Dead Synchronicity: The Longest Night is the prequel to Dead Synchronicity: Tomorrow Comes Today.
Dead Synchronicity: The Longest Night is done in style of a text adventure with graphics. As part of the Kickstarter campaign, you were able to get this game as a $5 add-on. Then for $25, there was another option to get all of your digital rewards on this really cool USB stick that looks like a classic cassette tape release that you might have seen back in the day on the Speccy or C64. I therefore treat this as the physical release of The Longest Night.
