But see, here is the difference: In Civ4, playing with an AI mod like Kmod, the King AI actually pursued objectives and posed a threat. Oh sure, if I was paying attention I could beat it, but it was a challenge.
I think I haven't explained myself clearly.
I know that in Civ5 I could play on deity and lose, and I would lose because the AI gets a massive amount of cheats.
However, I know that some random guy in Australia, who does not get paid to program, made a mod called Kmod for Civ4. In Kmod, the AI was a threat without massive cheats. It was a threat because it was ruthless and cutthroat. It would really maximize its military, for example, in every way possible, and then launch an all-out attack that I could only repel if I was playing my A game and prepared.
I've also played a lot of Galactic Civ and in that game the AI is also a big threat without cheats. It's not a sandbox game. The AI will do things on its own, things that force you to react and adjust.
My complaint is that the stock BNW AI is far too passive. It's like playing a sandbox game. Your retort is that I should play deity, but then you have missed my point. Plenty of other games/mods have created an AI that is not a sandbox, and did so without massive AI cheats.
Maybe you don't care about cheats. I would much rather play against an AI that is a challenge without them, than play against an AI that is only a challenge with them.
Anyhow, I will get around to playing Emperor with Acken's mod eventually.
