It's pinball, what's not to like?
Pinball FX isn't the best pinball game out there but it's still a lot of fun to play. The 3 included tables offer their own challenges and are all great to look at. The dot matrix display lacks colour though, and looks a little too basic for a modern table.
The ball physics are also a little unrealistic and it feels like you're playing with a metal-plated Ping Pong ball most of the time.
There are also an additional 3 tables that you can download from the marketplace, but it's the free one - Buccaneer which is the best of the bunch.
If you love pinball then you should certainly consider this.
