Quoted from Zablon:i think the key here is 'depth' and 'children' don't go together these days. Many simply don't want to invest the time in a challenge. I see a lot talking about how deep WoZ is, and frankly, that will be a turn off for most kids.
If it's for you and you are a pinhead, then maybe WoZ is better, but if it is for 'non-pin' family and friends, MB is the way to go - but I agree with some others, just buy both and sell the one that doesn't get played.
^^^ This.
Depends on if you think kids will really keep playing. I've seen advice on forums that usually steers people away from getting a game they think/hope the family will play. Many times, family doesn't, so get game more for you (WOZ), and hope family plays.
I'm lucky, my wife plays pinball with me & likes it. Older kids also sometimes play, but not as much.
