I'm a newbie to pinball (played my first pin in July last year).
We played a lot of the Williams and Pinball Arcade Apps before before our first pin (Fish Tales) and I've played two different Medieval Madness on site as well. Despite the moaning of people on here about how the love for Medieval Madness is all nostalgia, I have no question - as a newbie who is playing old and new pins together - that Medieval Madness (and AFM) were the best pins ever made.
They have brilliant toys, a widely-accessible theme (destroying castles, camp alien invasion), fun shots, great art, fun sound effects and are accessible to a wide range of skill levels.
On my first play of Godzilla, I considered it to be a Top 10 game. I now own a Godzilla Prem, which is our first NIB machine and a huge financial outlay for us. We've played it >530 times in the last month. I still want an MMr when we can afford one next year (and, hopefully, there's a reprint from the CGC on the way in early 2023), but I think that Godzilla is still marginally better than MM/AFM.
It does everything MM/AFM do, in terms of fun shots, accessibility to various skill levels, epic bash toys, art work and ridiculous sound effects (the Xilien Controller is hilarious) - but with the benefit of an LCD screen and modern coding. That's not to denigrate either MM or AFM at all, but in terms of sheer appeal to a huge number of people - ranging from my five year old to old timers rating on Pinside - it is an instant classic.
I can't fault it really, apart from the minor build quality things people are complaining about, which I'm hoping don't affect my machine!
