Armor and Weapon Qualities - Tags or Things?

[Duggan]

I have a number of "Qualities" that can apply to weapons and armor. They're basically your usual "Does extra damage to this type of armor" or "Needs to be reloaded if you roll double 1s" with a name, the effects, and a cost (for when you're doing custom items). I know that I can do these as a string field (and, in fact, that's how I did it when I entered the armor into the system), but eventually, I'll want to separate it out for when I have the gizmos to customize individual pieces (not to mention to make it easy for people using the editor to specify specific qualities). My first impulse is tags, but those just have a name and a value. Things could work too, bootstrapped onto the weapon or armor.

Is there a benefit to doing it one way or the other? Does that answer change if one is programming for the eventuality of customized weapons and armor?
