DartMUD
DartMUD is a MUD, a text-based online role-playing game, started in 1991 at Dartmouth College. It pioneered several interface and game play innovations which were later used to greater popular success by games such as Ultima Online.
Notable Contributions
DartMUD "Firsts"
The actual dates of the first implementation of these ideas in MUDs or MMORPGs are not well documented and competing claims exist, but DartMUD was first, among the first, or an early adopter of the following:
Permanent Death: DartMUD is targeted at hard-core mudders, people willing to risk permadeath — a common occurrence — in order to make their accomplishments that much more meaningful.
Hex-Based Wilderness Map: DartMUD implements a hex map in ASCII text an innovation which helped shape later games.
Numberless Interface: DartMUD differs from earlier LPMuds in that it is class-less and level-less. Attributes, skills, hit points, and magical aura are represented using generalized text descriptions, rather than specific numbers.
