caravan is more fun than poker. poker is all about luck, no skill needed. selecting what cards to play in the deck takes some skill. there is nothing like turning a 26 into a 27, for the other player. you can't do that playing blackjack or poker.
Maybe, but from what I've heard, Caravan is a pretty sure thing, once you figure it out. I prefer games of chance, where you actually have to play smart *and* get a bit lucky, to win. Gambling in NV is just a free (and quite boring) way to haul in buckets of caps.
