Well there are also logical proofs. And I said the game was objectively poorly received not objectively unfun.
Oxford commas are fun. But there's no design intent for making something poorly-received, so. Again, assumptive logic.
What was the design intent?
I answered this, in a part of the quote you didn't, uh, quote:
And impossible to answer for us, none of whom (presumably) are Firaxis developers.
You're also misusing "falsifiable". You cannot
prove a design principle wrong with
feelings. You can say "the game is unpopular", or "the game reviewed poorly". These are at least demonstrable, even if statistics aren't fully-formed and we only have what us, the public, have access to.
But slicing this apart into
specific design principles and their relative success is very hard to do. There have been multiple threads that have attempted this! And, presumably, something that developers who want their games to be popular (or more popular) also attempt to triage the same. Obviously, we can't rule out that some developers might want to intentionally create an unpopular product. A mainstream, well-known franchise like Civilisation is
probably (but not impossibly) not a candidate there
In this case, some other design intent must be behind those features.
Why? Designs can miss. It happens.
Without further primary source data, we have to use other dev statements inferentially, given a knowledge of the industry overall.
Why? There are a near-infinite of inferential possibilities given the possibility space that is "multiple years of games development". How do you choose?
(the answer is: subjectively, each according to our own experiences and worldviews)
Video game culture was never like this. Being mad that people don't like a thing you like to the point of insisting they stop talking about it is post-reddit.
I didn't say anyone shouldn't be talking about anything. Anyone else is not me, and I am not responsible for them, nor do I want to argue for them. But I do think wanting constructive, good faith discussion is a valid goal to strive for. Not really a goal I would think anyone would want to criticise, because of well, the inferences
Regardless, people have been mad at things to the extent they've wanted to shut down discussion about said thing for eons. Drawing the line there isn't our job as posters, either.
