Reiner Knizia's Money

When taken as a single-player card (cash) game with the potential for multiplayer in the future, Reiner Knizia's Money is definitely a game worth playing. It's much easier to learn than it first appears, and can be utterly absorbing if given the chance. It's no multiplayer tour-de-force, sure, but that doesn't mean it isn't still a heck of a lot of fun.
