Consider this stolen for d20Shawn 6th Edition

From Dwimmermount:

"I'll also note that the "Dave Arneson rule" for converting gold into XP is working beautifully. I only give XP on treasure that is spent. This means that every time they find gold or gems or whatever in the dungeon, they have to use it to buy things for themselves, whether they be scrolls, new gear, hirelings, or just a night out on the town if they want to gain experience points from them. This has served two purposes: 1) They must return to Adamas if they want to spend big sums of money and 2) They are perpetually poor. I am very satisfied with this, as I am with the campaign in general -- an excellent session overall."

Sayeth Old Geezer:

"Back in Brown Box OD&D, you NEEDED henchmen.

Thus, Charisma was VITAL, not a dump stat.

This is a case of the game being played WAY differently from how it was conceived."

Vecna = Vance

In games of Dying Earth, (player character)magicians must resist their Arrogance attribute in order to share spells with other magicians.

"Without the DMG, you're also missing the incredibly important Treasure Parcel table. The game kinda breaks without it."

"Well, not a Rolemaster level chart, but yes, a chart. Basically, you have the AC numbers running along the top and the various weapons running down as the column. When attacking, you find the row with the appropriate weapon, then run across to the AC number and that shows you what you need to roll to hit. Thus, swords work really well against unarmoured folks, but not well at all against plate mail. A mace, OTOH, is the reverse."

Awesome Ideas

At least we also get encouraged for giving out exp for Learning Experiences aka Bad Things such as being cursed (250 exp) and tripping a trap (50 exp). Reminiscent of the system in Tunnels & Trolls where you get points for a missed Saving Roll. You also get XP for casting spells (100 for a spell useful to the party in general like "Create Food & Water")

Dungeoncrawling in Tekumel

From Grognardi

In OD&D, one-quarter of all "magic items" consist of treasure maps. This percentage is reduced to one-tenth in AD&D, but that's still sizable. If you've ever wondered about the origin and purpose of the read languages spell, look no further than treasure maps: "the means by which directions and the like are read, particularly on treasure maps."
