Quoted from DS_Nadine:

Well The Big Lebowski had that feel, but that one's dead.
I really think Houdini has a lot of that "mechanical toy magic" (with it's center Stage, Catapult and Molded Decoration) Williams games had.
Willy Wonka, while not having played it, falls a bit flat in that area.
I mean, that MM Castle is a huge molded toy and it's kinda obvious what the player has to do.
JJP Pirates comes close with the ships...
Yes I hope for Deeproot. I also hope for JPop (oh I can see the downvotes coming).
Robert Müller seems to prefer Williams games, so I really hope we will get something like the old days again.
As for JPops, Magic Girls is a broken mess, but everything around it is marvelous. And while it is correct that it is not him drawing, making the callouts, composing the music etc. he just is a skilled art director. (I love the art, the music, the callouts, the lightshow... I love the big backglass without display, wich went in the game itself.) And imagine that huge center make really would have worked, levitating the Ball in the air and then lets it curl down the giant ramp... That thing was impressive even while broken.

Quoted from jgentry:

I think a lot of people just claim MM castle the best because of it's size. It's a super cool toy though and definitely one of the best, but there are a lot of other really good ones though.
