I don’t own a Stern game, but GB pro is the game I always wanted. I think the rules with the ladders are quite clever (three sets of modes with a wizard mode after is kind of unique). I enjoy GB the most every time I visit the dealer. I really like the music, so many different themes and variations. I like the right ramp - kind of like Diner - the cleaner your shot the better your score - I’ve wondered if you can get such a clean shot the ball goes all the way around. I wish I could get a GB Pro with magnaslings. I don’t like the ramps and the ectogoggles on the Prem - they block so much view. I think what has prevented me so far are 1. Spike, 2. Flipper gap, 3. Playfield issues, 4. complaints on Pinside. 5. the ball seems to spend too much time in the pops. While I’m still thinking about it I’ll continue to play it on Pinball Arcade.
