My wife & I played 5 or 6 games on an SE production pin at a location that was quiet enough at the time to hear the sound and call outs. It's not nearly as dramatic and intense or as theatrical as WOZ, Hobbit, or JJPOTC. It is definitely missing that. I think the sounds and call outs are "okay", as it isn't a big contrast to the theme. Yes it could be better in my opinion. Think of the monotone talking TV announcer in DI. Annoys people, but isn't a big contrast to the theme. The witch voice in WOZ annoys some. Sparky in MET, Jacky in AS, the bullying ego in the narration in ACDC. I like all of those as it "adds" something to the game. The DI narration really doesn't "add" to the game, and this will probably be the same way - the general theme makes it acceptable and won't grind at me over time. If it was going to be our only pin, it might get old. The Houdini narration and sound tone IS very annoying to me, but kind of goes with the theme. Oktoberfest is another annoying narration tone, but goes with the theme. Wonka should be fine for us.
What made me disappointed (yet also appreciative) is that the coders gave in to the demand of pinsiders that the SE will have wonkavator locks game carryover in the software and we saw that. Disappointed because that was one of the main reasons I put a deposit on an LE instead of an SE as at the reveal they said the SE would not have a carry-over locks. That was one of the perks for the LE. However, that being said, JJP is likely the only company that will occasionally give in to a big demand from their customers and listen to us and what we want if it can be adapted easily. I really do applaud them for that and it will make the SE game better for pinball leagues and locations. People for the most part just have to accept (but still complain about) some of the Stern game coding.
In playing the SE though, that back wonkavator corner is dark and empty. I'm sure modders will come up with something good for that area though. It's weird though because you consciously loose where the ball is in that back area on the SE. On the LE its the same blind area, but its got the wonkavator mechanism there so it is less of a "thing" on the LE (at least for us). I'm sure others don't feel this … it just struck us really oddly. Because of that (and the wonkavator mechanism and a few other upgrades), we are still going to be in on an LE vs. the SE.
Just our opinions ...
