HârnMaster is the best fantasy roleplaying system I've ever GM'ed. However, even the best systems need a few additions, deletions and alterations - House Rules - to tweak them to suit each and every gaming group. The following are some House Rules that I use (or have used) when running my campaigns.

HârnMaster 3rd Ed. House Rules		HârnMaster Advanced Rules
HârnMaster Gold House Rules		HârnWorld Articles
HârnMaster Core House Rules		HârnMaster Archives
GunMaster		JuggerMaster

Note that most of my House Rules are in PDF format. You will need the latest version of Adobe Acrobat Reader (which is free) to read them. There are also a number of files that have been bundled into a single ZIP file, which can be opened using 7-Zip (which is also free). A few others are in Microsoft Excel Workbook (.XLS) format because they perform calculations - you will need Microsoft Excel (which isn't free) version 2002 or later to use them.
