RMSS vs RMFRP

What is the difference between Rolemaster Standard System (RMSS) and Rolemaster Fantasy Roleplaying (RMFRP)?

These articles compare Rolemaster Standard System to Rolemaster Fantasy RolePlaying. They originally appeared as a series of articles in the Guild Companion. The first parts appeared in January 2002 and the last parts were in the June 2002 issue. May 2002 was the only month that didn’t have an installment. You can view the individual sections using the index below or the menus on the left or at the top. I have updated some of the articles since they were published in the Guild Companion.
