Civ VI was released in 2016 at the price of $59.99. According to this inflation calculator (
https://www.usinflationcalculator.com/), that's $80.18 today. Civ VII sells for $69.99.
Just another data point.
In Norway, where I live, it was 600 NOK for Civ 6, 829 NOK for Civ 7. If it were a similar increase to what you got in the US, to 700 NOK, I would not be complaining as much. However, while the price increase for the base game did indeed beat general inflation, the real price hike was for the DLC and higher editions.
For Civ VI, I pre-ordered the Digital Deluxe edition, which was the top edition offered. It cost 749 NOK, and included future DLC. The Digital Deluxe edition for Civ 7 costs 1199 NOK. Whether it contains significantly more content than the DD for Civ 6, you tell me, but at least it isn't obvious to me that it does. This was not the top edition of Civ 7 though, that would have been the Founder's Edition, which I can't find the price for at the moment, but I believe it was something between 1600 NOK and 1700 NOK. That's a lot. That's easily the highest asking price I have seen for any edition of a game I've considered buying. And again, it is not clear to me that what you got extra in the edition could justify the added cost. I certainly don't consider not holding the game hostage for an additional 5 days as added value.
As for the other points of comparison: For other AAA games, I simply tried to find one as expensive as Civ 7, and I couldn't. The closest I got was Avowed at 799 NOK. I didn't put that much effort into this, so perhaps there was some other expensive game I missed, but in any case, it was clear that Civ 7 was given the most premium of price points.
Finally, Ara: History Untold. I get that this is very much a challenger, and so it is natural that it would be priced somewhat lower. Some would argue that Civ 7 was a higher tier game and beyond comparison with a puny title such as this, but there's not much I can do about that. I myself would consider it a comparable game. Ara's pricing model seemed a lot fairer to me, with the base game at 600 NOK, and the very top edition at 719 NOK. That gave you some extra leaders, skins, an artbook and a soundtrack. If you didn't care about the art book and soundtrack, you could get the Deluxe edition with just the skins and leaders for 630 NOK, for the full game experience. There was no other DLC at launch, but instead a year of free content updates. Again...you may not think much of Ara, and that's fair enough. I do though, and it was one of the points of comparison for me when considering the asking price for Civ 7.
