I understand wanting to "get it right" but honestly, pinball has a "Quick and Dirty" kind of history.
Think about it: anyone care to look under their Firepower and tell us if they have the "brick bottom" version or plain?
Or if their Firepower has the routed details underneath to accommodate drop targets?
Do we want to talk about the differences on Sorcerer colors?

I'm pretty thrilled that a Nine Ball playfield is happening and don't have a huge issue with some of these minute details, say in the final 0 of 77,000...or even the lightning on the 9 Ball itself...who cares? It isn't going to impact your score for good or ill.

If it was printed on a t-shirt like that I'd wear the shirt.

What Mirco is doing seems like a much better deal than the missing text on Meteor playfields recently done by Stu & Co.

The collector cost of the machine today really doesn't change that Williams and others made color changes and other changes through the production runs of their machines.

If the detail is small and it doesn't impact play, who cares as long as the playfield was done with care?

All you need to do is look around and see alternate stickers for spinners--even spinners from other pins--and various other "mods" that have been made out of necessity or by mistake...this is pinball. Get that machine up and running!
