jsjrodman: I *think* in the original Bard's Tale 3, you could drop items off in the abandoned cache in Skara Brae? Or maybe you could only collect stuff from there? My memory is very muddled because while I've bought it multiple times, I've played using modified disks the most where that cache was clearly full of nonsense (it had all the artifacts).
Actually, you could not drop off items there in classic BT3; you could, however, pick them up. This was changed in the remaster, where retrieving items there is now possible.
By the way, in the remaster, if you transfer a save with items in the bank to BT3, those items will appear in storage in addition to the default items.
Also, *SPOILER*:
Having all the artifacts (except one) in the storage happens as a normal part of the game; it happens as soon as you gain access to the final dimension.
jsjrodman: This is moderately brutal in the Remaster in Legacy Mode with the Shared Inventory switched on.
I had hoped the shared inventory was just reduce the nuisance of inventory shuffling, but without per-character inventory, banking items on saved NPCs is limited to things they can equip. Luckily almost everything can be equipped, so I'm just creating one character per item with names like Silver Square. I may find out if there's a roster limit.
Actually, Shared Inventory is the default, and it's Legacy Mode that lets you disable it.
There's also a bank where you can store items after paying a fee, 10 in BT1 and 20 in BT2. Items in the bank (except quest items) will transfer between the games if they're in the bank (and will end up in BT3's storage shed, as I just mentioned above).
