This is an alternate set of resolution guidelines, adapted from the book The Games of War, by John Bobek. It uses only 2d6, gets rid of HP and the Combat Matrix, and changes the way ability checks and Saving Throws are done.
An update: We playtested this and, frankly, I was underwhelmed at my own work. I couldn't keep track of all the plusses and minuses, and it actually seemed to slow down combat a bit. I'm sure it's fixable, but the experience made me realize I don't really have any problems with things as they are. Maybe I just needed to get it out of my system... Anyhow, if you find them useful, run with it, and I'd love to hear about it.
