Quoted from Stepan:

Besides new "Mini" wizard mode, and relatively tame overcharge mechanic, what else is new from a gameplay perspective?

I didn't notice any major score changes. Game is still a linear snoozefest. Hurryups are useless, theater awards are useless, drone area is useless, crazy modes are useless

Quoted from Stepan:

Do you shoot for that or do you try to collect your lit simcard worth 100k? If you dont have a sim card, do you shoot theater over shooting B-O-B targets to relight kickback or QED to light phone? What has been your biggest score from spider, kilowatt, etc value?

Have access to one at the arcade. It took us a few games to even game to Chaos in Quantum City, and before we did, none of us noted any significant score changes. As a competition player, from my experience and everything I watch and read, you score significant points in the most linear fashion from any Pat Lawlor, modern Stern or JJP game ever.
I was hoping that this update would remove some of this linearity, but instead it added another wizard mode tied to doing modes, and ability to score a bit more points in the modes.

Unless you turn on Sim card memory, do not have a tilt bob installed, had the best game of your life, or is a pinball god this is not that significant. Our location DI had a grand total of 1 Showdown played, ever, since it was delivered, and I was there for it.

Whatever adjective you use to describe it, they weren't significantly (or at all?) changed in 1.5, so my point stands.
