After running my first heroic game last weekend, the question of "how much money do we have?" came up again. I've sorta gotten the impression Kiznit doesn't want loot to be a focal point in the system (noting the lack of treasure tables and a price list, and the flexibility of the wearpons/armor system). But I think it's an important thing to include for a lot of players.

So I had a couple ideas. My first idea was to include a much-simplified price list, and leave the rest up to the DM. Something like:
1GP - Cheap adventuring stuff: rope, 10' pole, fishing gear, torches, rations, staves, slings, a meal, an ale, and night at the tavern)
5GP - Basic (thieves tools, lanterns, tents, carts, donkeys, swords, axes, a night at the brothel, a night of drinking)
25GP - Cool (horses, most light armor, elven wine, holy water, spyglass, bribing a crooked guard)
100GP - Expensive (warhorses, most heavy armor, an exotic animal, a carriage)
1000GP - Really expensive (a boat, a house, something magic)
10000GP - Super expensive (equipping an army, a castle, a dragon's hoard)

My second idea was to adopt this to a "wealth system" like you see in d20 modern. Personally, I hate hate hate wealth systems. They're confusing for the players and they're incredibly easy to abuse. But in a rules-light system like OSH, where the DM has a lot of veto power, I think this could work.

PC wealth is measured like this:
A little (1)
Some (5)
A lot (25)
A whole lot (100)
Tons (1000)
I'M RICH BITCH! (10000)

When they get money, the DM tells them (for example) "You each get A Lot of money". So each PC checks off the first three boxes on their sheet.

Later, when they spend money, they might need to erase one or two boxes.
*if something is two categories below what you've got, don't sweat it
*if something is one category below, you need to erase your top box
*if it's equal to your current level, you gotta erase two boxes

I think this will work out with the PC's typically getting Some or A Lot of gold in their early adventures, and spending it when they get to town. They'll have incentive to do so, since getting Some money when you already have Some or A Lot doesn't do you any good. So you may as well spend it every time you get it.

If they really want to pool their resources, the DM can let them combine 5 or more (typically, the whole party should throw in) of one category to buy something from the next category. But that probably shouldn't happen often, especially when bumping up A Whole Lot and Tons. When pooling resources in this way, everybody has to erase one box.

Similarly, if one PC wants to pay for the party's night at the Inn--well, that's costs Some gold instead of them being able to pay for it A Little at a time.

Finally, PC's always have the option to get a "fancy" version of anything. Fancy versions of things are always one category more expensive than normal.
