I'm at over 2 weeks owning a GB pro, and on location at my studio lobby (we are a video game company) me and a few other employees have racked up 800+ games. Here's my thoughts:
It's challenging. I love the design of the game. It is pretty easy to teach newbies the rules (I'm always amazed how many people didn't know pinball had rules...) and its really difficult to master those shots. Currently no one has completed a 'tower' of story modes. I have read that you get the "we came, we saw, we kicked its..." multiball mode once you complete all story modes in a stack, but no one has yet managed to complete " back off man...", "The Ballroom", or "Gozer".
Its a calculated, punishing game. Which has made multiplayer a lot of fun. Its pretty difficult to trap the ball reliably. and there are not a lot of super safe shots. so even if you are being calculated and hitting high scores, a single slip up WILL end your ball. resulting in short games all around, with very wide ranges of scores at the end. Mostly people who are just flailing at the ball end up with low scores, and people who know what they are doing have high scores. despite the game times being pretty much the same.
While being challenging is great, the table also comes with some really wicked unpredictability. during the first 100-200 credits, the surface tension on the playfield did really weird things to the balls motion. The ball would bounce off a slingshot at full speed, come to a dead stop in the center of the playfield, then fall and drain. That weird surface tension seems to be wearing off, but odd spins and sudden changes in direction still happen from time to time. I've been thinking of cleaning the field and seeing if I cant buff it all to normality.
The most common way to drain balls is the outlanes. Audits showed something like 80% of drains are the outlanes. I put a clear acrylic mod over the left outlane rails, but the right guard rail is still getting jumped from time to time, ruining good games. I had to take the right side protector off because the screw that holds the end of the ramp was not long enough to accommodate the acrylic guard. I'll probably resort to taking the original artwork acrylic off in favor of the mod. which is a shame to sacrifice art for function.
Airballs are a major problem. I have ordered a mod but it has not arrived yet. I have had a LOT of great games ruined by the ball flying up and bouncing all over the place. I am really anxious to see if my games improve significantly once I don't have airballs anymore...
I also find the nearly vertical slingshots tend to slowly 'juggle' the ball upward, and after 10 or so back and forth, they almost always fire it directly into an outlane. I've taken to nudging hard whenever they start passing back and forth to break the momentum. seems to work for the most part.
The flipper gap does not bother me. Its there, and I notice it. But besides the RARE 'Straight down' from the bumpers area, I pretty much never find myself cursing the gap.
The Scoleri Bros are awesome. I fucking hate them, they ruin everything, but when I beat them and get that super Jackpot... thats a good pinball moment.
The left kicker started kicking right into the drain at some point. I lowered the power so now it just drops into the left flipper. I actually prefer it.
The right mini ramp is extremely difficult, but I forgive it because its a relatively safe shot.
The left captive ball is not very difficult to hit, but its extremely dangerous to do, and you are required to do it a lot if you want a high score. I'm really struggling with that shot at the moment. but it seems 50/50 as to whether it bounces right off into an outlane after. I tend to get my best captive ball hits by accident from the slingshots.
I think that the 'Bonus Points / HELD / Multipliers' are ruining the competitive play of the game. we are averaging 40-100 mill regularly, with the occasional 400+MILL game where we didn't even understand where those points came from. They always involve a multiball but in general the games were not very well played it was just a ton of multipliers and HELD rewards. My last game today I was pissed as my last ball drained thinking I had just played a mediocre game only to look up and see 500 Million on the scoreboard. I had like a x15 multiplier somehow...
In general I love the game. But it might be a little too punishing, and random. I want my wizard modes to be hard to get to. really hard. but I have been playing the hell out of this thing and I have not even gotten close to halfway there yet. And all my best scores were by accident. Its weird. Not getting rid of it anytime soon. and when I do, it will only be to buy a Premium for my home. Its a great game, but may not settle in my top 5 long term.
