Quoted from pinlawyer:Houdini has one MAJOR flaw, despite its beauty and great code: geometry. Whoever designed this PF was no engineer. The shots simply feel wrong. And when I heard it was designed without the benefit of a whitewood, even, it all made sense. If AP survives to make a second and a third pinball, I will buy their products as I did Houdini, because of the code and the attractiveness of the game. Geometry, I would hope, is a mistake a company makes only once.
Anybody who cares about gameplay knows this to be true.
The real question is, does it matter? If Houdini sold well, I'm sure AP will keep cranking out rough draft playfields and focusing on other aspects of the game.
Dialed in clearly plays like it was designed by a master and refined to the point of perfection. Night and day really.
All depends on what you are looking for in a game. If you are enthralled by the Houdini theme, or captivated by the art package, sound, or animations and don't care about gameplay, it's a no-brainer to pick Houdini.
There's reasons for some not to want a Dialed in but gameplay/layout are certainly not among them.
