I played the Pro back in March, liked the way it shot but the code wasn't really there yet. I have a R&M due before Xmas but decided on impulse to pick up a Premium last week to help get us through the winter as my wife is a big fan of the show and there isn't much else going on at the moment. Installed the UV kit on the weekend and so far no regrets at all about the purchase.
It isn't the deepest game, but has plenty to do and shoots incredibly well. Love the left orbit to right ramp shot, it's very satisfying. The projector is pretty cool even if it isn't a total game changer, and the UV kit is stunning especially with Titan glow rubbers. It's a nice change of pace from the deeper / more complex games like JPLE and JJP POTC that have been getting most of my playtime so far this year, and I'm having a ton of fun with it. It's a great game to play in a dark room after a few beers, that's for sure.
I think people did write this title off a bit too soon, but for understandable reasons. The combination of early code / production issues / UV kit as an addon purchase kind of killed the enthusiasm pretty damn quickly, and I have to admit I never really thought I'd end up buying one. Glad I did though, it's turned into a solid game with great atmosphere and a great lightshow.
Cleland sound mod does massively improve the game too. Everyone owner should give it a go.
