Provocative title, I know. But this will be a serious discussion. Civ 5 introduced a key change, that was perpetuated in Civ 6. That change was the switch from an isometric map to a hexagrammatic map.Now why is that important? Simply put, the new map design takes away moves per tile. Instead of 9 possible moves, we now have 7. Now this may suggest the game has become more simple, but in effect the opposite is true. With regards to the AI at least. But Civ 5 introduced another change, which was perpetuated in Civ 6: the solution to the Stack of Doom in the most simple (and effective) way. No more than 1 military unit per tile. Again, this may seem to simplify the game, but again the opposite is true. Why is this so? It is the intuitive thought to think the game has now become more simple rather than the opposite. But what we're discussing is the AI, not the human side of things. The reduction in possible movement combined with the removal of stacking means the AI should have been greatly improved to deal with thsi greater challenge. And it is here, that both Civ 5 and Civ 6 have been lacking. The game as it is now poses a bigger challenge to the AI. and yet this was not accompanied by a hugely improved AI - neither with Civ 5 and not with Civ 6. (Although I would argue that the AI has improved in 6 over 5.) I would say that the key problem is solving the Stack of Doom issue without realizing a better AI in the process. Perhaps this issue was not acknowledged by the developers, for whatever reason..It's impossible to tell, but it is an oversight. But it only becomes a key issue when simultaneously replacing an isometric map design with a hexagrammatic one. Having less possible moves with no stacking ability poses, rather obviously, a bigger problem for the AI than for any player. And now this becomes a major oversight, rather than a possible one. Because prior to these game changing new features should have come the development of an AI, at least up to Civ 4 standard, but essentially better. I think it's not an overstement to say that such an AI doesn't exist in either Civ 5 or Civ 6. So, in essence, this is as good as it gets. Because with two expansions released and no major updates to the AI, I think it would be wishful thinking to expect the AI issue to be fixed in a patch or two. One can only hope that Civ 7 will be better than the past two. and that will require some major changes. For the better this time.
