Legend
Title |
The MUD's title; if it has had more than one title, the most recent title. Disambiguation is included only when MUDs in this chronology have the same title. |
Founded |
The date the MUD was founded or first made publicly available. |
Closed |
The date the MUD ceased to be publicly available. A blank entry indicates the MUD continues to operate. |
Business model |
A brief description of the MUD's business model. "Free" means the MUD has no revenue stream. "Subscription" means that the MUD charges a periodic subscription fee for access or for a set level of in-game benefits, such as a "full" or "non-trial" account. "Pay for perks" means that the MUD accepts payments (which may be called "donations") and provides in-game benefits in exchange for them, on an à la carte basis. "Donation-supported" means that the MUD accepts payments, but its policies exclude providing in-game benefits in exchange for them. "Donation-drive supported" means that the MUD accepts payments, with policies excluding providing in-game benefits in exchange for them, only at specific times for specific purposes (most typically hardware upgrades), and does not accept payments at other times. "Freebie marketing" means that the MUD, by its existence, provides a purchase incentive for external goods. |
Developer |
The company that carried out development of the MUD, or if the MUD was not developed by a company, major individual contributors, if known by real name; "Et al." indicates other contributors, often a large number of participants in a project community. |
Publisher |
