If you're a pinball fan, I highly recommend Flipnic. This isn't a simple mock-up of a pinball board. It's a fully 3D pinball style action game, including fun multiplayer.
First, the pinball. You get a number of "worlds" to play in - natural, metallic, light based, and so on. You play on a number of different boards in each level. The boards are all attached to each other by ramps, so the current board you have on screen is always manageable and visible. You can easily get to the ramps to send you off to another board, and rack up the points. There are a number of cool interactive features on each board, including special multi-ball and other situations. You really get the hang of each board combination and style.
The visuals are really quite nice, from the bumpers and flippers to the surrounding environment. The sounds go well with each world, too.
Just as good, though, are the multiplayer games. Each world offers one. There's a basketball game, a 3-tier pong game, and a game that is in essence two simple pinball maps side by side where you try to get your opponent to lose balls faster than you do. The one that shines is the foozball game, though. It looks simple enough at first - you raise and lower your bumpers to move the ball into your opponent's goal. Once you get the hang of it, though, it is amazingly fun.
Well recommended for any pinball fan!
