I don't get why people think the gameplay is horrible. Maybe they haven't played a game that was set up properly? And weak flippers? That's a flipper/configuration problem, not necessarily a WOZ problem.
Ultimately, I notice that when you hear people criticize WOZ, all their arguments are mostly subjective. They "don't like the gameplay." They never seem to point out specific issues that most people might agree with. Don't like a widebody? Again, kinda ambiguous and highly subjective. Don't like the theme? Again, very, very personal.
I've had this argument with people before... I respect everybody's right to have their own opinion on things, but it seems more honest to just say, "I don't like the game" than it is to say, "The gameplay sucks." That implies there is some universally-accepted problem that they've refused to or cannot address. I don't get that.
For example, I can point out specific things about specific games and why I don't like them: some games have very repetitive rulesets that get boring. WOZ doesn't. Some games have certain areas that are the "go-to" places for shots if you want to score points - and the scoring system is unbalanced and competition is un-exciting because there's basically "one way to play the game" if you want to score points. WOZ isn't like that. Some games have video modes that are not random and can be memorized and therefore represent no real challenge. Those are specific, non-subjective criticisms. I rarely hear anything like that from WOZ critics. It's usually "I don't like it" without any real details.
As far as tech issues, I've never had any problems with my WOZ. I had the crystal ball come un-glued. I glued it back. I've never had any lighting go out. Considering how exponentially more-complicated this game is over anything Stern is currently producing, it's amazing for an inaugural product, that WOZ has so few issues.
