I think this is not a problem of the way they monetize the game (frequent small patches and pass rather than big expansion one a year - which I like and I think it's overall better approach), but what is a part of this pass content. Some ppl want devs to be more focused on improving the game as it is. The problem here is for example dull mid and late-game which is hard to improve because it is a part of the core game design - win condition to be precise, which makes the game a snowballing race for resource generation with AI. This is the main lesson they should have for Civ 7. The second issue is AI (better Ai will increase the difficulty level of the game because AI will generate resources faster, and could military stop your snowballing more efficient) This makes the game too easy for elite and minimaxes. There is a Mythic Plus difficulty level in World of Warcraft dungeons which is a good idea for Civilization imo. Next levels of Deity Plus (no chopping, no selling goods to AI, limited turns etc.) would increase the difficulty level for the elite in an infinite way but also keep a stable and not punishing progress for casuals or new players.
