I liked the way they handled it in Nehrim (although I haven't played it for awhile)
And how exactly was it handled in Nehrim?
I do not want banks. They're not good for the game system. It's already kind of irritating to me that the shopkeepers will pay so much less than an item is worth and then on top of that, they have a max they'll pay out regardless of what happens.
I do like the idea of coins having weight - 100 coins to a pound seems reasonable. The player should then have an option of storing the coins someplace however - even in bags we set inside our house or stash somewhere, just like every other NPC in the game.
If banks are installed however, why would
any NPC ever carry that much cash or leave buckets of it at their home?
I like the idea of coins having a small and reasonable weight. I also like the idea of the player being able to drop coins or stacks or coins, or perhaps sacks of coins in their house if they so choose too.
