Caravan was great back at launch on xbox, the opponents didn't play properly and you could effortlessly clean out entire inventories of shopkeepers because they'd bet their store earnings. Then I moved to PC and it was a lot less braindead & not worth the effort, it actually knew how to use the face cards.
I forget how to play every single time I go back to fnv and I always try it enough to relearn and then never play more. It's honestly so one dimensional.
