To everyone that's freaking about caps instead of coins I only have a few things to say to you guys.
2. You all say gold is easy to find, have you ever tried to find some? It's a metal that's ungodly hard to find at present and it's only 2010, think of how hard it will be to find in 260 years or so. Sure they had it in fallout 2 but that doesn't mean that it'll be everywhere in the US. I'm pretty sure it'll be just as hard to find if not harder to find than it is today.
3. Gold only has worth because some moron 10,000 years ago liked a shiny rock. When you use that logic it seems like a ridiculous reason to give something value. I for one after a nuclear war wouldn't find a worthless hunk of metal useful, you can't even make it into something useful because it is to soft for conventional tools. Food would be higher on a list of valuable items in the wasteland, especially if you didn't want to eat something 200 years old.
4. As for caps, yeah I know it's not completely with lore but new vegas wasn't mentioned in any fallout previous to this one so for all we know they still use the cap system and will change over if the NCR takes over. But the dev's have already said that it's going to be caps and not coins so if it bothers you that much then just mod the game to have coins when it comes out. Or roleplay that the citizens of new vegas are using caps backed by gold or something along those lines.
First there are gold mines all over California, there was a gold mine in fallout 2 (Redding). Gold would be in every damn bank and casino all over california and other states before the war. NCR has the techonlogy and smarts to melt it down.
Caps only have worth because some moron in fallout said they were worth something. what is your point about the gold? Yeah someone gave it value because it was "shiny" but that guy/gal also figured out you can make jewelry out of it. Try giving your girlfriend an engagement ring made out of rusty bottle caps and see how well that goes over. Gold you can do more with it then money. you can make jewelry. Hell if you wanted to you can use it to make power cables it's better then using copper for conducting electricity. Caps you can't do anything with them.
You are dead wrong about Vegas not being talked about in any fallout. If you have ever taken the time to play fallout you would have known that New Vegas was talked about in Fallout one by a man named http://fallout.wikia.com/wiki/Tycho He talks about "Las Vegas" and he also talks about information from the game Wasteland.
The Devs should keep with canon, you say that the money does not matter well it does. They take away one thing before you know it. All the canon is gone and it's no longer Fallout. Coins were a sign things were getting better!
Like I have been saying for all those that have only seen how fallout 3 works. Step back play fallout one and two. Hell play tactics and enjoy them. Learn from them. Wiki can't give you information if you don't know what it is you are looking for!
