I bought mine in February of last year, and sold it in June. There are two things that I really did not like about the game.
If you're someone like me, you play games with an eye toward completing them; in WhiteWater, that involves reaching the wizard mode. One of the tasks in getting to the wizard mode in WhiteWater involves lighting the RIVER letters to progress the bonus multiplier. The letters are inserts directly in front of five stand up targets on the left side of the playfield. In the usual way, you can light those targets by hitting the stand ups. Problem is, controlling the ball after you shoot those standups is a bit of a nightmare. The other, safer way to light those standups is by feeding the right inlane; each time you do, you light another letter.
The easiest way to feed the right inlane? Shoot straight up the middle with the right flipper. Ball kicks to the upper playfield, rolls down to the right inlane. Repeat. 25 boring times. Then, if you can do that without falling asleep (trust me, it takes a while), you can get to the rest of the stuff in thhe game, which is actually pretty fun.
The other thing that I didn't like, and I still cringe about almost a year later, is when the ball went down the Insanity Falls ramp on the left of the playfield and cracks into the glass. I'm sure you could put a piece of mylar there or some such thing, but why anyone would deliberately want to have a game make a horribly abrasive noise is beyond me.
