vs Darkmaster is a Merp alike (and thus RM alike) game/clone with the Tolkien stripped out and a few things cleaned up.

HEREIt was out of stock for quite a while in dead tree so I got it in pdf and print/bound it in hardback myself. I also took the opportunity to split it into several books (as others have done when they took it to a print shop) to make it easier to handle. I also use the opportunity to put my own stamp on things so made my own covers and so on. Been doing this for a while now.
From the brief skim through I've had (too many games not enough time, usual story) I'd have thought if you ever played MERP or Rolemaster you should be able to pick this up pretty well. D100, open ended, look on charts, aim for 100+ on Move Maneuvers and all that.
Because all the Tolkien stuff is stripped out there's also rules for cooking up a big bad evil guy, the 'Darkmaster' in the title. The PDF is about £13.80 at the moment on sale (or about $15 or whatever) which is pretty good as the page count is high, art is pretty good and it's a 'one book' game. Or rather it was - there's a few bits out for it I think.
Quickstart is pay what you want (i.e. nothing) on Drive thru so might be worth a look. Here you
GO.
