Middle
Earth
Role
Playing, an RPG by
Iron Crown Enterprises.
Iron Crown pretty much has a
monopoly on "
official"
Tolkien role-playing game material.
Mechanically, MERP draws heavily on Iron Crown's "Rolemaster" (Spell Law, Arms Law, Claw Law, etc.) rules. The detail of herbs and enchantable materials is terrific, but some of the names... well, Tolkien would roll over in his grave! "Mirenna" has that Elvish sound, but "mook" and "fraw" just shatter the mood.
