Like many of the members of the DIY D&D (OSR) scene out there I have been playing games for years... decades in fact. I have seen games come and go and have given many of them a try at one point or another. One of the games I bought and tried to play, but could never really get my group into when I was a kid was MERP (Middle-Earth Role Playing) by ICE. The games mechanics were grounded in ICE's pretty popular, at the time, Rolemaster game system. As a Tolkien lover I just had to pick up the game. Though we never really played I ended up using a lot of the material as a spring board into developing some of my own hacks for D&D.
One of the tables which I worked into my own game was the table on page 77, "MT-2-STATIC MANEUVER TABLE".
