I really enjoy the Fallout series. I played a lot of FO3 but just recently got around to playing NV. After roughly 400 hours of the Fallout series, I've had a revelation: bottle caps is a retarded form of currency. My character is running around right now with about 10000 caps. Could you imagine what 10000 caps would be like? Here's a visual:

That's a lot of caps. Not that I'm complaining about the inventory system... carrying 200 lbs of gear is ridiculous to begin with, and it is just a game. I just find a huge pile of caps on top of 200lbs of gear is hilarious. Instead of spurs that jingle-jangle-jingle, his pockets do.
And can you imagine counting out a few thousand of them for a purchase? Have you ever been behind someone at the checkout line in a store and they pay in pennies? Buying $30 of stuff and paying for it in pennies would be the equivalent of counting out 3000 bottle caps. Thankfully we are blessed with a mysterious teleportation system that immediately transfers the correct number of caps instantly. IMO, it would be awesome if every time you confirmed a purchase the time would lapse about 3 hours to account for having to count out all those god forsaken caps.
I know this post is dumb, and I'm sorry. I just had to share my awesome insight with peeps familiar with the game.
