Quoted from DaveH:WOZ was the game I owned when I started getting a dislike of upper playfields. They block sight of the ball for too long. So yes, I've never owned Whitewater or BK2K, and wouldn't specifically because of that issue.
And to be very specific, on WOZ I didn't mind the left one that much, but the right one blocking sight of the the ball as it came down from the lanes or orbit to the upper right flipper. It's pinball... so am I wrong for wanting to see the f'in pinball?
WOZ has a horrible upper playfield, off the plunge the ball is blocked, I hated that also...Don't let that game hinder your thoughts on upper playfields; some are done very well!!
