I was thinking that there should be more and better bows, as well.  My original idea was to be able to equip Arrows as an add-on inventory item like the various "Ranger Pack" is, that would add to the firepower, perhaps add in armor piercing.

I thougth muskets and gunpowder would be interesting additions.  Perhaps we could make a steampunk age technology level or mod. 

Thats the idea I'm trying to work out how viable it is to add the option of a zero magic 100% industrial revolution kind of conquest into the game

Based on (what little) I know about modding the game, making new stuff isn't really a big deal (which is amazing, actually).  Editing and duplicating XML is easy.

So adding a new bow, and calling it a gun is a good start.  Then you'd need a model.  I'm not sure about that part.  I'm still trying to figure all of this out.

Making industrial age techs would probably just extend the tech tree. I think magitech would be a neat idea, like steam engines powered by fire elementals and stuff.
