So I agree with everyone - iteration isn’t good or bad in itself, it’s all about the why, what, and when. No mountains moving on that assessment.
Personally, I would have pegged myself as an originalist. Just knowing that I prefer T&E over Y&Y, Agricola over Caverna, Bruxelles over Federation, Race over Roll, Ethnos over Archeos… I have this picture where it starts with a vision that is closer to art. Once that vision is proven, it’s molded by the realities of the market and mass consumerism to become something more universal, more palatable, yet…less? The spark is taken out in favor of accessibility. I’d rather have the mountain to climb rather than the boardwalk next to the parking lot around the lake, you know?
Yet as I honestly go through the list, the counterexamples pile up. Gaia Project over Terra Mystica, Winds of Galecrest over Libertalia, Quo Vadis over Zoo Vadis (no dissent there, I’m sure), Birm over Lanc (maybe? Still sorting this one out, honestly), Neom over 7 Wonders, New Frontiers over Puerto Rico… that list goes on as well.
There’s a reason my book took four drafts. You get better as you go. Some things you can’t see, or learn, until you have something tangible in front of you. Sometimes you need a crowd to find the Halifax Hammer for you before you can patch that hole.
Yet there still has to be a reason why I celebrate Rosenberg’s or Knizia’s endless niggling with a design while I refuse to give Leacock 25 of my own cents.
The most prominent rationale has been stated: Is it different and/or better? That’s an obvious (and good) test, but also backwards looking. I can’t blame someone for trying even if the revision didn’t hit the mark. Mori comes to mind - I think Archeos was a good faith effort and just a miss.
Using Leacock as the canary (man, I wish the idiom were ‘peacock’ there), he is iterating on one thing and doing it too many times. Contrast to Rosenberg, he has 3-5 archetypes and is iterating on each one fewer times. I think the latter ratio shows an honesty and integrity that someone is generating and refining ideas, as opposed to milking an increasingly dehydrated cow.
I could also critique Wallace and Stegmaier in that it seems every item out of their gate ends up being iterated. At a certain point, it looks more like they are releasing unfinished products rather than continuing to work good ideas over time.
Lastly, I’m wondering if there is a “how long has passed” question. Quo Vadis to Zoo Vadis, Lancashire to Birmingham - that’s one thing. Azul, Azul, Azul, Azul - that’s something else. Yet Terra - Gaia - Innovation is somewhat rapid as well, and those are some big and valuable evolutions. Maybe time doesn’t matter.
End collected thoughts.
