I agree about the farming business, as soon as I came to those treechopers I could by all the items in the game and the rest got boring :S But I do like that the farming activities motivates training in the game.
With some modification most of the members that have submited a message on the postquestion seems to like the idea.
As I mention before the shop will only be activated when you replay the game.
I was thinking something like this:
After completing the game your characters can take their weapons and armour with them to the new game.
Some of the monsters will have some chance to drop all kind of weapons/armour/items with diffrent attribute, and that is where the shop comes in handy.
Adding some kind of townportal spell to the runelist that goes to level 0 where the shop is located, also the skeletonkeys will go to teleportation devices on all the levels so that you easly could go back and fight some favorite creatures.
The shop shouldn't have a so big storage, more like a room with some alcoves that have some items you can pick and pay for. If you leave the room without paying for the items, you will get some angry and very hard to defeat guard after you.
Suggestions and remarks are welcome
I also have a question to Trantor. What is this slotmachine you talk about? How does it work?
