Just a thought today, nothing really more. I've been reading some adventures recently, for a mix of systems - AD&D, D&D5, GURPS, DCC, and others. I'm more conversant in play with some of them than with others.
One thing that trips me up is - how much is that treasure worth? If someone is paying 250 gp, is that a lot? 500 silver? 2000 copper? Is that a valuable gem worth dying over or just a bit of extra take-home loot?
In games I've played a lot, I can eyeball this. In the ones I haven't, I try to flip around the books and see what that will get you, or what you've expected to spend.
In my own DF game, it's easy enough to relate to weapons and upkeep.
At $150 a week, a full year of upkeep at a normal, fairly pedestrian level of living is $7,800. I've got rules in play for each rough doubling of upkeep to cover lavish living. The top end is $5,000 per week, which is $260,000 per year.
Top-end normal weaponry runs in the high hundreds - and magical weaponry and prefixes on swords and bows can multiply the cost many times over.
Armed with that information, I find it easy to relate to the actual spending value of the money found.
Without it, and without sufficient experience in play, it's hard for me to eyeball.
