In 2007, the second edition rules system was revitalized and issued under the name Rolemaster Classic, or RMC for short. The revitalization was published by Guild Companion Publications and included new versions of all the old core rulebooks of "Arms Law", "Spell Law", "Character Law", and "Creatures and Treasures", but also an updated "Rolemaster Companion" and a new "Combat Companion" from 2008. Also in 2007, Rolemaster Express, or RMX for short, was issued by Guild Companion Publications. It is a simplified version of the Rolemaster Classic system, with all necessary rules combined in one single book.
