I just received my GB Premium last night. Set it up and inspected it. Looked perfect. (My last Star Trek Premium I received as NiB took 3 weeks and a dremel tool to "tweak" small things like the lockdown bar that wouldn't lock down, or the ramp with a 1mm gap between it and the playfield, and wiring harnesses not connected, and bulbs that would mysteriously flicker, and ripped decals, etc...). I really was prepared for the worst but it arrived in great shape.
Now, let me emphasize that I am currently thrilled with it and think it's great overall. But ughhh. This was my first two hours with it, amounting to a complete comedy of errors:
1. Cut the wire tie to on Slimer that was so tight it flung off onto the playfield. Spent 30 minutes looking for it and couldn't find it.
2. Plugged it in and discovered that the on switch is now under the back of the box... completely out of reach as I had already moved it into position against a wall. Unwilling to climb over the machine and after failing to get it turned on with a broomstick handle, I had to move the machine about 2 feet away from the wall. I'll need a solution to this eventually as I don't want to have to turn it on and off via unplugging the power cord.
3. Turn it on and experience about 5 seconds of horror as nothing happens. I got used to the Star Trek one that is much more instant lights-on.
4. First ball drains instantly (clever Stern!). It is saved and I'm ready for the second shot - prepared this time. I miss it again. My first play of the game is a double drain without a single hit. This game is hard.
5. I hit the ball for the first time! It slams against the side of the large ramp (all the way in the back) and is launched... LAUNCHED... across the entire playfield and lands behind the flippers. Wtf? I knew about some airball issues, but this made me very gun-shy.
6. Into the 3rd ball of the first game and the entire thing restarts for no reason that I could discern. I'm not having much luck.
7. Game restarts and 2nd ball in gets stuck on the missing wire tie! So glad I found it. I remove the glass and the errant wire tie.
8. I start another game. With the ball on the flipper and me taking in all of the options and targets, the machine enters ball find mode, which apparently involves slimer moving onto the playfield. DON'T hit the slimer target when slimer is out on a ball find because slimer will then crash to the left and the game will reset.
9. Things went great for about the next hour, during which I learned how truly hard this game is and how I will likely never see all of the scenes the game has to offer without cheating. I also learn how awesome the under-playfield magnets are.
10. I regret not taking a picture of this. Had I, you would have seen the ball on top of the ecto goggles glass nestled comfortable by the LCD screen. I did buy the protector from Stern, but they took about a week to ship it, so I don't have it installed yet. No apparent damage.
11. In my enthusiasm to get started, I realized that I had not leveled the play field yet, and the back needed to be raised about an inch or so to get the bubble where it is supposed to go. Tried to play again and it was substantially faster (less air balls, though!) and I couldn't get the ball more than halfway up the big ramp.
12. I wrapped up the evening with around 2 hours of gameplay. I realized at this moment that I had neither gotten any multiball nor did I experience the scare feature. More reason to keep playing though!
So I really am very happy with it. I wish some of the fun modes/scenes were a bit more accessible to casual players, but overall I think it is a great addition (despite my hiccupped first evening with it).
