Bingo. The AI just keeps shoving it’s ludicrous deficiencies in your face over and over. It makes it real hard to turn a blind eye to it when it keeps forcing you to deal with the incompetence.
My complaint isn’t that the AI in Civ5/6 doesn’t play at an expert level, it’s that it doesn’t understand the very basics of the game. I’m talking egregiously stupid shit, like declaring wars when it can’t reach you, leading an attack with un-escorted Great Generals for a long time in Civ5, or sending defenseless Settlers wandering through my territory shortly after declaring. Civ5 modders fixed these issues using the tools provided by Firaxis, which proves all it takes is some effort on their part.
Fixing glaring issues like that wouldn’t make the AI play at an expert level, but at least it wouldn’t be so embarrassingly neglected.
