I am running a Swords & Wizardry Light game for Free RPG Day. I am using my Siege of Crasmere as the starting game. So I created these resources I can use for the game. I created (click generate a lot of times) the map at http://wizardawn.and-mag.com/
On the reference sheet there is a table with Goblins and Orcs on it. How I plan on using this table is anytime the characters kill off a goblin or orc I will tally it up. At the end of the battle if the characters decide to go around and loot the dead bodies then I just add the tally marks up and multiply that by the amount of gold that can be found on the goblins and orcs.
