I have a pet peeve: the 8 Strength commando toting a Desert Eagle and wearing heavy armor. Yes, I've seen it and yes, it annoys me.
So, all weapons and armor in Modern 2.0 will all have a Strength minimum.
The Strength min will determine (along with your Strength score natch) what weapons can be used one-handed, two-handed, two-weapon fighting, etc.
Armor's ONLY requirements will be Strength and money.
No feats. That's dumb too.
