Careful with this one, you may burn a entire afternoon without knowing it.
The core game consiste of 4 tables, with the possibility of expanding it by buying estra tables (including the ones for the original game, now improved to match this new tittle). FX2 is a good example of how to improve a mediocre game into a really good product; Zen Studios really succedeed in picking the good things of the previous one (not a lot, lets be honest) and fixing warever was necesary to fix.
Better phisicks and better graphics makes this a really fun to play game good for both a entire afternoon of gaming, or just a quick one (if you can drop the controller once you start, that is)
At least, I suggest, get the demo and check it out.
