WH2O, but let me explain. There are pins where you *think* you are close to achieving a tough goal and achieving a high score, but you fall short, so you try again... and again... and eventually get tired of trying (so you stop playing that game). For example, in WOZ, actually completing Rescue Multiball is very challenging, and whenever you fall short, the steps to get back to that point start to feel tedious. All the while, you're racking up very low scores (thanks to the programmer's philosophy that low-scoring is something pinball players would like). You might start to lose interest. On the other hand, there are games where you never get tired of trying. For me, WH2O is like that. The goals are within reach, but a lot of times you come close to achieving Class VI River only to drain and start over again in Class I. It's enough to piss you off, but the game is so much fun, and there's always a chance that a Mystery award will help you out, so you hit the Start button again and again.
