I have a Premium. I bought it because of the code and wanted a more challenging game then the Hobbit i replaced. The pop bumper SDTM drains have alot to do with being perfectly level and i also added a thicker rubber to the right ramps left post by 1/16" so i dont get them anymore. The left ramp some people have trouble with making the shot clean enough to get up the ramp ive heard also. Also the prison magnet i here alot about SDTM which only happens for me if i dont press the flippers back and forth during the animation.
Change the music and callouts to RandomKG Radiohead/NIN mix with callouts from actual show, add a subwoofer and the audio really comes to life. Also nice mods are yokos crossbow and gnassels light mod for bicycle girl.
Gameplay and code wise the games got 5 regular modes, multikill mini modes, and 5 wizard modes. Everything has been coded really well on the entire playfield. The game is brutal when your not making your shots but when you get a few things stacked together the game is really intense. Whats nice about it is you can use different strategies each time you play to progress different ways depending on which wizard your trying to achieve, its not a 1 trick pony.
