Yo HR, not sure if you read through all my crap, there were some good ideas, some we talked about in SMP.

Couple things I thought of. Most importantly items in JA are static[...]

Another thing which comes to mind is that you may need more than one resource for "merging". Think of making a cartridge, you need primer, case, powder, and the bullet. However for pre 1900 you may need to make a paper cartridge, where you need paper, powder, wad, shot.

NAS has a weird thing I discovered, you can right click on an attachment slot and it will bring up a pop up menu.

For example I added a RAS bipod and a gripod and got a bipod bonus of 100% because the attachments were not mutually exclusive (oversight) and the bonuses (spell?) stacked.

A good item system needs to allow the definition of how adding (changing) an item will affect its other properties instead of transforming the item into another item ID or adding values to its properties.

Back then I used the example of a belt, a carbine hook, a water bottle, and a bottle stopper with a latch. Adding the carbine hook to the belt should *not* change the item ID of the belt, it should just be an attachment (not in the JA sense), which gives the belt new abilities.
