Oh? By that logic literally every setting should be the default option right now. No exceptions if that logic applies.
You're taking this out of context. Remember, we have a problem here where players don't know what the implications of the setting are. Since we don't actually know what the "balanced" setting does with certainty, players can't make a reasoned choice over which setting to pick.
We know the likely implications of changing rainfall, sea level or opponents, so it's fair to leave those choices in the player's hands.
Even so, it's pretty arbitrary to act one way for this setting and completely different ways for other settings. Perhaps HoF should lock ALL settings into defaults? Certainly, that would provide consistency although options like ruins/barbs/etc are fairly clear sources of noise. Although such a rigid system would probably need refining over time, it IS probably a better opening than banning things wily nilly.
All rules are arbitrary. You judge them on the basis of the results they generate. In this case, we want to produce the best gaming experience possible. Consistency is a desirable property in a set of rules because it makes the rules easier to remember...but it is not universally the most desirable property.
Source? I'm actually curious about this from a non-civ standpoint.
You don't want to try to read that stuff if you don't have to. The math is brutal if you're not used to it. I'll walk through a quick example that we're all familiar with as proof that the set exists.
Suppose we have two people: a construction foreman, and a business owner. The foreman oversees a team of workers building a shop for the business owner. The business owner can't be on site all the time to oversee the foreman's actions, and the foreman can save enough money cutting corners to afford a hefty bribe to any third party paid to watch him. However, the owner does have time to spot check the foreman's work.
If the timing of the spot checks is known to the foreman in advance, then he can save money by having his employees cut corners in ways that can be covered up, and be sure that any incriminating evidence is hidden when the owner arrives.
That's bad for the business owner. It's also bad from a societal point of view; cutting corners in construction saves the foreman much less than it ends up costing the business owner in labor to undo the shoddy work and do it right, so productive capacity has essentially been wasted by the foreman's decision.
The business owner can make some progress on this issue by making the spot checks random. At that point, the foreman can only safely cut corners if the evidence can quickly be covered up should the owner arrive. That eliminates a lot of the possible harm the foreman could cause, saving the business owner a lot of money and society a lot of labor put to an unproductive use.
We can conclude that making the enforcement rule non-transparent is better from a societal point of view in this case, and so the set exists.
The implications for hiding enforcement rules in HoF exist, and they are pretty dark. For a video game competition where one is encouraged to push the limits it would really come down to a game-spam issue. Sooner or later people will realize when things get rejected or not. Arbitrarily inducing tedium to find this cutoff? No thank you.
You can live in one of three worlds here:
- The zero tolerance world
- The world where the ruleset is hidden, with the implications you indicated
- The world where we define the tolerances and make them public, resulting in players literally trying to herd the barbs onto the tile on the right turn to get the 300
All of those outcomes suck. The question on the table which one sucks least. The claim I made is that the second world is better than the third one. If you systematically push the boundaries, you risk having the HoF staff push the big red button and disallow all of your work. Since players don't know where the boundary is and the downside risk is large, most of them will behave. The scumbags will get thrown out, and good riddance. At the same time, you don't have to scrap your game just because you forgot and re-upped a single deal three turns early, which is what happens in the zero tolerance world.
Also, how do you separate a "lucky" guy who got pillaged on turn x from a guy who deliberately allows it? Or do you go back to banning both regardless? Even so, people are going to game this. You and I both know it; it would be foolish not to do so if you want a top spot.
It's possible to self-enforce, and I think that's what you have to ask. HoF provides a public record of everybody's games. Go look at the gold medal game I have and root through the completed Deal History. Two deals stick out like sore thumbs. In one case I gave Darius 3

to finish off a Research Agreement. In the other case (turn 79) I got pillaged. Count how much Cotton I have, and how many Cotton deals I signed before 31 turns later. If the two numbers are equivalent, there's a problem.
If you're doing it all the time, or just in most of your really good games, you're going to get caught. You're right that we can't separate out the occasional accident from the occasional malicious instance. That's intractable. But people can't game the system often.
