All live dealer games are played between two live users. You play against a person. People have noted that a game between a person and a computer loses a lot of the original charm, which made casino games so beautiful. However, the chance to play against a live player makes it that much more interesting.
Many games are now able to work with live players. There are, of course, blackjack and poker, and there is also baccarat now available. All the action is shown from multiple angles, and several cameras show the ball spin from different views and you can even see it happening in slow motion.
