I've had a WCS for the last week. I got it perfect and pretty, cleaned and re-rubbered, and soft white led'd about a day later.
It has been played nonstop by my wife and her girlfriends, my twin 7 year old nephews, and anyone who has been over. I've put maybe 15 games on it. The outlanes are wide open, the settings are not "easy", and the flippers are set perfectly flush to the lane guides for harder traps.
It is challenging, unlike what others will say. The purpose of the game is straightforward for casuals and the rules seem pretty deep for me, as a player/enthusiast.
That said, I bought this with the intention of non-pin people, kids, and women to play and get excited for. This will pave the way for TWD (and other "hard" machines) to be added for me, haha.
FT is definitely a fun game, but grows old quick. Like most games of this vintage, it turns into only shooting for mb, wash, rinse, and repeat. WCS probably has a little more staying power in that regard.
