I still haven't learned to play caravan. But yes, those are what the cards are for. The game seems complicated, but I guess once you learn it, it's not too bad.
And go see the cashier at a casino, they will exchange NCR money. You can also trade them to traders, but the exchange rate is based on your barter skill.
As for loading screen tips, I have the PC version, so they go pretty quick on my PC. Although it's a little slower than fallou3, so I can read the shorter ones in time usually.
Yeah I didn't know how to play it either until yesterday. I forced myself to watch the "how to play caravan" video on YouTube.
What confused me the most about it was A: controls (It would be much easier if you could use the mouse methinks), and B: The initial card choosing. I didn't understand what and why I must choose.
Now I'm not good with cards, never liked card games and don't know squat about them. You could say I'm a total noob in cards. But I'll try to explain briefly for people like me who's not on speaking terms with cards (Though seeing as everyone I know knows how to play cards, I'm a little worried that I'm in a minority

)...
In short you choose any cards you want from 30 to 60 or just pick random (which I prefer obviously). Then you need to build 3 caravans/stacks with numerical cards. The sum of each stack should be 22-26 with the higher the better, meaning 26 is the best. Stacks must be built in ascending or descending numerical order (for example: 2,3,5,7,8 or 10,9,7,4,3 etc.).
And that's pretty much it, the basics.
To win, the sum of your stacks must be higher than opponent's. Meaning - for example: if you have stacks of 26, 24 and 22 with opposing enemy stacks of 24, 22 and 22 you should win... I think.
I won with only 2 full stacks, so I guess as long as your sum is higher you can win with 2.
Also there are bonus cards or faced cards as I read somewhere.

Anyway those give you bonuses to your stacks. Like queen reverses the descending order to ascending and vise versa. King doubles the value of the card it's placed on. Jack removes the card it's placed on. Ace adds 1 point. Joker is... I don't know what it does, but it's better not to use it.
You can sabotage enemy stacks with these cards. Like for example placing king on opponent's 22-26 stack making it go higher than 26 which forces the opponent to disband the stack and start a new.
EDIT: lol "opposing enemy stacks"


This game is wonderful. Doing well in my current game. Me with an Anti-Materiel Rifle and Boone with the Gobi Scout Rifle along with ED-E's sensors just essentially kill anything outdoors within a few seconds. Shame about the bugs though. But I can wait for the patches. I also regret not using Helios One to power up Archimedes II at first. Turns out you can't change the route later.
I'd love to hear everyone's favorite weapons. The Marksman Carbine and Riot Shotgun are so good.
Not sure about the favorite weapon, I kinda use what comes by since my little incident with the brotherhood.
I ended up in brotherhood bunker with Veronica while I was completely out of ammo. Conveniently enough upon exiting the bunker we were confronted by 4 mean paladins... I thought I'll never leave that bunker. Fortunately the mighty "quickload-repeat" does wonders. The best and only solution for me out of that situation proved to be "run for the hills while Veronica deals with them, as they insisted on shooting me exclusively". Since then I wasn't picky about weapons I pick up.
