I played an LE for about 2 hours the other night, I want to preface with I am a longtime GNR fan with a pre order in that I intend to convert into an order for an LE.
Like any pinball machine, there are good things and bad things, mostly depending on your preference.
I liked the lights, I didn't love them. There were one or two instances where the light show was AWESOME, and generally the lightshow was good, but it could be better. I hope they keep working on this. I loved the mechanical spot lights, that was fun.
The game played well. It's not Elwin good, but it's good. Speed wise and layout wise, it's a lot more TZ than SM. Some people will like that and some won't. I don't love the mini, I think there is much better use for that space, but I did like the ramps and there is a shot through the pops which I personally enjoy. It had a couple really hard shots, like the left loop, I like that as well.
The rules are what you would expect. Elwin can take a complicated rule set and make it feel like progress on his games, he sets the standard in my opinion. Compared to Elwin's games, GNR has a lot to do, but it feels more like chopping wood than a journey. However, it's about the funnest wood you will ever chop. Obviously the game needs and has a lot to do, and it is fun, but sometimes goals feel arbitrary. However, risk vs reward is my favorite when it comes to rules, and risk vs rewards is very alive in this game and deserves a mention as a huge plus.
The audio is a bit of a let down in my opinion. Lots of songs, 21 I think? But, the same number of songs from Chineese Democracy as Use Your Illusion 2? That's not right, this game should have all (or at least 10) songs from each from the Illusions (I believe it already has 10+ from Appetite). Also, the call outs are bland and oddly lethargic. However, it still has 21 more GNR songs than any other pinball besides the first GNR. For the content that is there, I enjoyed it immensely. I love that Coma and Estranged are there, I love that Double Talkin Jive is there. When you start a song, it feels great. The audio quality is great, starting a song is something too look forward to, even if I wish there were more songs.
Most people will like this game, some people will hate it and some will love it.
