Why do you hope all ammo crates are gone?
Because:
1. it's been 203 years, most of them should have been worn out.
2. makes no sense for a random ammo crate on a table to
not be looted or for it to be there in the first place.
3. since there was so many of them you just got craploads of ammo without having to do anything for them, killing a raider at least poses a challenge, you have to spend ammo to get ammo.
I mean, if a wastelander had some .22 bullets in a metal box or something it could make sense but almost everyone had ammo crates.
How?
How do almost every wastelander and his dog have an ammo crate?
Did the army have a huge sale on them before the great war?
Are they made from some strange foreign world material seeing as none of them have degraded under the 200 years that has past?
Oh and why the hell does every single one of them have ammo in them?
I mean, so just because it's an ammo crate it rejects anything else bing put inside of it?
How come I could never find an ammo crate with some mirelurk cakes in?
Or one with some cigarette packages in it?
Or how about this, finding an ammo crate that is.... Wait for it... Empty!
They pissed me off, logic-wise, lore-wise and balance-wise.
