We have been playing MERP (Middle Earth Role Playing game) for some years. Essentially all the old Editions by ICE (Iron Crown Enterprises), that use/extend Rolemaster.
There are some lists of prices in the rule books, but there is nothing in terms of wages/economy, etc.
Our current group plays a very open sandbox-style campaign centered around the economy of a shire in Arthedain, (comparable maybe to medieval Europe).
Do you know of any good lists of prices and wages, if possible in the Rolemaster/MERP currency (Gold/Silver/Bronze/Copper/Tin pieces)? We have been inferring prices through a mix of research into medieval economy in England/Scotland and 'translations' from other systems. This quite imprecise and laborious as well...
...And a 10-Foot Pole
This seems to be the go-to book for Rolemaster prices. It is out of print and amazon lists used copies starting at 100$ and more. BUT, I was able to find a PDF version on scribd! Check this out!
