Core MUD - Steve Edition
========================
.. raw:: html
Old COREMUD has moved to coremud.org:3000 (3022) TLS.
Steve's single player version of core is being developed here, that is
a version of core that has has been shorted to play over a month or less
and doesn't require multiple players to run the economy.
Expect player wipes as things are adjusted, and massive balance changes.
Driver: fluffos 20240714-4a59909c-12dbae53-uncommited, Mudlib: Colony 2.1
