I think this could be quite possible if the script is running on your end and users open a conversation with you to play, but you would really need a database (preferrably a proper database as opposed to some form of flat-file database) to store players' statuses ie. their location, items, level, etc. and it would probably be useful if each location in your game was also stored in a database ie. ID, Location Name, MessageWhenUserArrivesAtLocation, IDOfOtherLocationsUserCanTravelToFromThisLocation.

If you use a mostly database-dependent approach (where all game data is stored in a database) which I think is the key to any MUD-style game as it allows easy editing and building upon, then it shouldn't be too difficult once youve figured out how to connect and query a database from within a Plus Script. But be warned before you begin that something like this (regardless of your approach) will require many hours of scripting/coding.
