This is a video capture of the editor for the game "Das Land" I wrote back in the 90ies in Turbo Pascal. It was one of my most ambituous projects in terms of story telling and contained a huge amount of maps, characters, dialogs and quests.
I managed getting it running on DOSBox, that's what I used to capture the video.
I cannot take credit for the graphics, unfortunately. Most of them were taken from similar games at that time and modified to match my tile resolution of 20x20 pixels.
