Yeah, ideas are simple only because one fail to see their complexity, and it depends from a point of viev, your experiences. Don't ever forget that.
On the little topic of weapons boosting strenght. I think this should be redefined. Sch a weapons are fine, but wit little differet approach, the magical strenght you get from magical weapon will aply only to what you can do with it. For instance it won't make you to wear more stuff, but will make your blows stronger, parrying better. This sounds slightly fine that there may be magical force, which make your whole body stronger, thus allowing you to move, with more in your bag, but it's a little clitche.
