Dialed in is the better overall package, and as other have stated has much more flow than Houdini, but for a first game Houdini is very good. A friend of mine said that Houdini is a wide body game sandwiched into a regular, I think that is pretty accurate. The shots, especially on the right, are so tight that I feel it crosses the line from challenging to frustrating. Dialed in just plays so smooth and getting Big Bang to complete a mode is just so satisfying!
Both are good games, no wrong answer here
