I played both on location (about 15 games of Houdini and about 20 games of DI) and bought a DI, which just came yesterday. I have no doubt that I made the right choice. Houdini was a beautiful game with a lot of cool ideas but there was no comparison as far as gameplay. I’m still getting the hang of the shots on DI but you can left ramp, right ramp. side ramp, right ramp, left loop this thing for days and it’s so smooth. I got no flow from Houdini and I’m a flow whore. The artistry is top notch on both games. I might warm up to Houdini more if I owned it but on location I tried and tried but just couldn’t sync with the machine. The Batman 66 next to it though....
