This is a strange question and it may be in the wrong forum, but I was wondering if there was a such thing as a combat simulator for D&D (or Pathfinder). What i mean is a computer program that you can input characters and creatures and hit the "go" button and see how -- statistically speaking -- the combat is likely to turn out. Obviously weird stuff happens at the table and with real people, but even so it seems like a useful tool in adventure and encounter design. Has anyone heard of such a thing?
