Stern does a surprisingly good job of making the premium/pro dif less about gameplay and more about neat pinball moments/toys. I rarely feel like anything is missing substantially from a gameplay perspective on a pro, and OFTEN feel like it shoots better. I have a GZ premium on order and I keep going back and forth on just keeping my pro. It's the better pinball GAME imo, but the premium is the better PINBALL game...that is, those Mechs are just neat and part of why most of us get into it. But as someone who likes a challenging, fast game, I genuinely prefer to pro. Absolutely get why a lot of folks would prefer the premium - but really, there is suprising little difference in play between the two. It's impressive considering what is actually missing.
I'll be interested to see how pro vs. premium plays here - it looks like it's missing a ton, but then so does GZ.
