The old WEG adventure module "Crisis on Cloud City" had a small-sized sabacc deck and rules for play. But that was late 80's-early 90's. I laminated my cards when I worked at a public library (using the library's patron-card laminator, making the playing cards something like the size of a credit card). This made them very stiff but very durable, and had the bonus effect of making them feel like sci-fi playing cards.
