Is tehre any difference, and will they have the same effect even if i use it within america and such? I heard its a different smell but is it a big difference or is the smell just as good as the effect as the non world edition?
It’s just the smell.
IMO smell of World edition is floral, Reg AMMO smells like detergent
ok whats world edition? and why are they out of ammo i need more!!! I love this shit, it makes me like james bond 
World edition is just a different scent package.
Is it a good scent? Will it be just as attractive as the usa version?
In my opinion I like FF22 (World edition) better than FF21 (normal ammo scent)
It has the same pheromone content so it doesn’t matter what you get
