I like the plants vs Zombie and Deadpool the most, A few of the starwarz tables are fun too. I prefer pinball arcade more. I think the Zen tables lack sound feedback. They really need deeper audio that includes more stingers. I hate the 'thud'thud'thud' of the ball against table parts without a stinger to suggest some activity.
I play both and like what FX does to try things that aren't possible on an actual physical machine and enjoy the animations, but some can be distracting.
