So far, I have completed and posted seven resource card sheets. That includes two armor sheets, two sheets of gems and coins, two equipment sheets, and a sheet of weapons, for a total of roughly 350 cards.
I have at least 17 more sheets in various stages of production. Many are just cards with item names at the top of the box, although I have populated some of those cards with images as well.
Here are some of the other categories of card sheets I am still in the midst of, or am considering, producing: Equipment, Weapons, Magic Armor and Shields, Jewelry, Lodging, MU Spells, Cleric Spells, Elf Spells, Rumors, Clues, Plot Points, Non-Magical Treasure, Magic Weapons, Potions, Scrolls, Miscellaneous Magic, Whimsy, Spell Components, Hirelings, and Special Abilites.
The Non-magical Treasure cards will include such things as pelts, artwork, spices, cloth, drink, and the like.
The Whimsy cards will be similar to the Ars Magica whimsy cards referenced here.
The special abilities cards may be similar to the 4e feats, or may simply be the special abilities possessed by certain classes or archetypes.
The Lodging cards will represent the sorts of places you might call home, such as a tent, hovel, barn loft, floor of a tavern, common room, Room at the Inn, Room at a House, Run of the House, Barracks, Cloister, Nunnery, Manorhouse, and so on.
There will be several sheets of miscellaneous magic items.
What have I missed?
