I'm going to predict a new combat system. I think it would be a mistake to go back to stacks of doom, but I think they'll want to try something else.
I just hope that once they will introduce some form of Generals, or units upgrades system, they will stick to it, and make the game HARD for players.
Then just use the game difficulty bar, to adjust AI about using all of combat mechanics, or dumb it down, so it would never build an army, for example.
Every single Civ game in the past have had the AI feature of building strong armies, removed in one way or another, before abandoning development.
Civ VI had a very bad Carpet of Doom update at one point, in trying to make the AI stronger. It was completely removed.
Now, if I start a Civ VI game, I would like to be able to choose the AI difficulty more ferally.
I would rather choose to have COD instead of this final AI iteration.
A more complex options menu from the beginning regarding AI perks, would be neat.
Try to include as many variations as possible, with effectiveness bars, for example.
AI can build armies - slide from 0% to 100% probability.
AI will prioritize aggresive behaviour - 0 to 100% probability slide.
AI will prioritize SOD tactics - 0 to 100%
AI will prioritize COD tactics - 0 to 100%
AI will go WIDE vs TALL - Wide vs Tall slide.
AI will ignore leader agenda - 0 to 100%
AI will ignore Wormongering - 0 to 100%
AI will try Hystorical accuracy - 0 to 100%
AI will use patch X, Y, Z, K, but ignore Q and F... in other words do not force all updates like windows 11, but leave players the power to choose which patch to apply from start to finish.
When an History record of patches like that is made possible, a lot of people will now have a multitude of open options to choose from.
Alternatively, allow modders to be able to acces all of these properties, and do not restrict them.
But this has to be made possible in Vanilla from day one, otherwisethe game will go on development, and reach a point where it
will be too complex to make changes to the 'base' game, and nothing will be done to fix new issues.
Civ VI base game only traders would build roads, and these would often choose sea routes if shorter, negating the players
important roads, and nothing could be done to fix this bc 'base' game was not modifiable.
A detailed History record preference menu could minimize the rollout problems.
