DGD (Dworkin's Game Driver aka Dworkin's Generic Driver) is an object-oriented programmable
MUD engine which is primarily used together with a
mudlib to host online roleplaying games. Although it is classed within the
LPMud family, the DGD driver was written from the ground up and is not really a direct descendant from LPMud.
Dworkin, the author, enforced a rather bare bones approach to the construction of the Driver, as it never was meant to only be a MUD driver (hence the 'generic' part of the name). Unfortunately, the lack of decent
mudlibs has retarded its use.
