It's been growing on me for quite a while now.
I've had my WOZ for 2 years, I love the game, I love the theme but it's also turning slowly into a frustrating experience as I'm nowhere close to completing all the modes, and some of them feel out of reach.
In between I bought a TSPP, which is my first standard body, I started realizing that it makes a huge difference in play, in speed and "frenzy" once the ball hits the lower playfield, it feels like playing pinball on steroids, even on a TSPP that is far from being the fastest game around.
Then comes DI, I hated the game for a while, I would barely play it on location and always felt bored shooting randomly and just trying to keep the ball alive. Until a day where I saw the light, played an awesome game, and started to really get into it, read the rules, and really got to enjoy the game. I'm actually a much better player at DI once in a while on location, probably 150 games or so, than the 1500 games I've put on my WOZ without really getting any better.
Same with TSPP, and I must say playing good games almost everytime is very rewarding and a good reason to want to play more.
So here I am, wondering if I should part with WOZ and get a DI, I know I will always enjoy playing WOZ, but the growing frustration that comes with it, makes it tough to start a game with the hope of nailing it.
