Long post inbound.
Okay so, people have mentioned that Steamed Victoria's ability is obviously very strong, but I wanna give everyone a picture of exactly how strong.
Here's a conservative example. Say you have a city with a +3 Production Industrial Zone. Then you slot in Craftsmen to double that adjacency bonus to +6 Production. Already, not an insubstantial amount. But, of course, this isn't a blank city. It has 1 Mine and an instance of Iron you haven't even improved yet. That mine gives its grassland hill tile +2 Production, totaling to +3 Production. The Iron, also on a grassland hill, produces +3 Production thanks to the extra Production on strategic resources.
Add that all up, and our city is producing +12 Production.
And then we build a Workshop. That gives us +3 Production, increasing our total to +15. Steamed Victoria's ability gives us +10% Production, making our total +16.5 Production.
If we weren't playing Victoria, we would have only made 12 Production. Victoria, in a small, 2 population city with only one mine, one nice Industrial Zone, and one source of Iron, is giving us +4.5 Production.
But what about a more liberal example?
Say this city instead has 4 mines, and one of them is an Iron mine. They're all on plains hills too, so the tiles naturally have +2 Production. We've recently researched Industrialization and built Ruhr Valley, meaning each of our hills with mines produces +6 Production, and the one with Iron gets an additional extra +2 from Vicky. From mines alone this is +26 Production.
The Industrial Zone has an adjacency of +5 doubled to +10 with Craftsmen. We have a Workshop giving us +3 and a powered Factory which gives us +7 (normally +3 but Workshop of the World buffs it). Our Industrial Zone, including buildings, is giving us +20 Production. Combine that with our mines and we already have +46.
Say this city also gets +4 Production from domestic trade routes. Our total is now +50.
Ruhr gives us +20% Production, and Steamed Vicky's bonus from IZ buildings gives us another +20%. 140% of 50 is 70 Production, 12.4 of which came from Vicky.
TL;DR:she's really good
