An online text-based role playing game is a role-playing game played online using a solely text-based interface. Online text-based role playing games date to 1978, with the creation of MUD1, which began the MUD heritage that culminates in today's MMORPGs. Some online-text based role playing games are video games, but some are organized and played entirely by humans through text-based communication. Over the years, games have used TELNET, internet forums, IRC, email and social networking websites as their media. There are varied genres of online text-based roleplaying, including fantasy, drama, horror, anime, science fiction, and media-based fan role-play. Role-playing games based on popular media (for example, the Harry Potter series) are common, and the players involved tend to overlap with the relevant fandoms. Varieties MUDs Precursor to the now more popular MMORPGs of today are the branch of text-based games known as MUD, MOO, MUCK, MUSH et al., a broad family of server software tracing their origins back to MUD1 and being used to implement a variety of games and other services. Many of these platforms implement Turing-complete programming languages and can be used for any purpose, but various types of server have historical and traditional associations with particular uses: "mainstream" MUD servers like LPMud and DikuMUD are typically used to implement combat-focused games, while the TinyMUD family of servers, sometimes referred to by the term MU*, are more usually used to create "social MUDs" devoted to role-playing and socializing, or non-game services such as educational MUDs. While these are often seen as definitive boundaries, exceptions abound; many MUSHes have a software-supported combat system, while a "Role-Playing Intensive MUD" movement occurred primarily in the DikuMUD world, and both the first Internet talker (a type of purely social server) and the very popular talker software ew-too were based on LPMud code. Although interest in these games has suffered from the popularity of MMORPGs, a large number of them still operate. Play-by-post and PBEM Play-by-post role-playing games or PBP RPGs refer to another type of text-based gaming. Rather than following gameplay in real-time, such as in MUDs, players post messages on such media as bulletin boards, online forums, Chatrooms (such as like AOL, hangouts and Yahoo chat) and mailing lists to which their fellow players will post role-played responses without a real limit or timeframe. Of late such blogging tools and sites as LiveJournal have been utilized for this purpose. This includes
