This hits a problem I've started to notice with magical items (other than they not really tell us the ingredients needed to make the items listed by a player): 4th Edition is so High Fantasy that the magical items seem very nerfed compared to past editions.
One example from the new Adventurer's Vault: Pouch of Platinum.
What does it do? It takes gems or gold or lesser metal pieces and "exchanges" them for their equivalent in Platinum Pieces. If there isn't enough money to exchange for a platinum piece, those pieces remain as they were.
The level 4e decided that this item is appropriate for? 5th level.
In 3.5e the closest I could find to a pouch with similar items is the epic artifact pouch that multiplied one gold piece into ten gold pieces. So from 31/2 to 4, we've gone from something that may well would have been considered an artifact (epic artifact at that) to a magical item that adventurers might pick up after defeating a creature with the abilities slightly better than the average bear!
This is in a world where most towns and villages they would into would sell most things for copper pieces or silver pieces at best! Cities are very far and few between, and yet this could be put into an adventurer's hands who could well be in the middle of their Heroic tier? I could imagine...
Raliena drifted into the local village tavern with a slight grimace on her face. She just took out the bear who killed her pa, and then vanquished the warlock who commanded the bear to kill him in the first place. All he had was a pouch might well could be magical, but in this two-horse village, probably didn't have a wizard or cleric who could discern whether this pouch was magical or not.
"Here's your ale. That will be 5 silver pieces, lass," the wench said through her beard. Hadn't dwarven women heard of the idea of shaving? Raliena thought as she reached into her new found purse. Her eyes widened as she couldn't feel any of the gold coins she had put into that purse. She pulled out a lone platinum piece that was there in the pouch, which was impossible, the pouch had nothing in it before she put her loot in there.
The wench and pretty much every patron had stopped to look at her. Raliena weakly mumbled, "Anyone have change for a platinum?"
(By the way, one other little complaint: They renamed the immovable rod as the
immovable shaft. That's just not right.)
