Ah, realism, makes sense.
But, one problem, wouldn't a bag of 2000 caps be big as hell?
That's it!
I require a caps bag, the more caps you have the bigger it gets, if you have 50.000 caps then it'll fill up the screen.
That's what my reply was going to be. What about
bulk? That's realistic, too.
If we're going to have weight for everything, let's see the Courier lugging it around as well. How big do you suppose a pack would be that held 5 or 6 guns, thousands of ammo rounds, a couple fridges full of food and magazines, 3 sets of armor, multiple quest items, etc, etc?
Try to outrun that Deathclaw now, buddy.
I play games for fun and the satisfaction of overcoming occasional frustration. Not for drawn out, grueling exercises in psuedo reality. Optional mods to give everything weight are perfectly fine, but I wouldn't use them.
