Explorations: redink1's Basement
Redink1's basement is exactly what it says; you have the opportunity to visit Redink1's basement. It is no D-mod, nor does it have any gameplay; you point and click to zoom in or out or to get a description of what is in the basement. This type of adventure play can however be used to create a D-mod that does have gameplay. This D-mod comes with not compiled code so you can see how to create your own. Therefore I would say this is somewhat more a tutorial then a D-mod.
