Sojourn, a
MUD (Multi User
Dungeon or
Dimension). The original Sojourn was one of the most popular
Diku MUDs which focused on
hack 'n slash and roleplaying, based loosely around the
Forgotten Realms. It has since then died but created many
hybrids. Initially it split into two seperate MUDs,
Duris and
Toril. Toril was for
roleplaying, Duris for killing. Neither MUD exists these days, but there is a Duris2 and a new Sojourn (which is more like Toril), plus a Basternae2.
Sojourn and it's clones have caused many
people, mainly
students and
geeks, to
drop out of high school, fail their college classes and to generally
screw up their lives simply so they can have another few hours
online. It has been known to cause these people to stay up for days on end MUDding.
Many online
games have this effect, though.
