This is why I think there are two pinball philosophies that exist. While others are not wrong in their assessment of JP vs DI, most make an assumption on these threads everyone is a pinball purest and a pretty good player who can progress a linear game like JP.
I am not saying DI is a top 5 pinball machine of all time, but I am saying JP is NOT a top 5 either.
My issues with it, which might help the OP:
#1 -The lack of real movie assets are a problem that only either Elwin fans, or good pinball players who prefer complex rules- are OK with. For everyone else, it will get frustrating and boring, with no real nostalgic WOW moments. #2 - The game shoots clunky, period. There is "decent" flow, but if we are being honest, unless you own a Pro, the Premium has no flow. #3 - Probably most important, it gets far too repetitive. The atmosphere is world-class for about the first 50 games and that's it...especially if you suck and you cannot progress in the game...it becomes the same game every time you press start.
Now, for a STERN, yes it is a beauty to behold. It is one of the better tables toys wise and theme "under glass" they have made. With that said, JJP theme integration and toys are better almost in every table they have period. It's just a different experience that you can't judge until a JJP sits in your home.
Back to the skill level point. My wife really wanted to like it, but since the game is so linear, she can't even capture two dinosaurs. I understand that's a skill issue for her, but there are pinball tables where you can feel some sense of progression within your first 20-25 games even if you are a bad player. This (JP) is not one of those tables. DI actually is, she is quite good at it ironically.
Oh and did I mention the code? I think I did, but it's worth mentioning again! You get suckered in by the theme, then you find out it's unintuitive. Every single house party I have, folks gravitate toward JP in the beginning, then after they put two games in, no one is playing it. They would rather play Mando, GOTG, The Hobbit, GNR, TMNT you name it...they have no idea what the heck is going on on JP.
With all that, I'd say buy DI, and play JP on location and after $30-40 bucks of play if you still love it...just spend more time at your local bar playing . Unlike DI, that JP table is everywhere!
