You get diminishing marginal utility per AI time increase.
I know. I know the concrete numbers of exponential growing combinations. I know the general life experience, that 80% of anything I do is done in 20% of the time and the remaining 20% of anything need 80% of the time, because they contain the problems & exception handling etc. etc. etc.
The AI is not 50% better than pre-patch or whatever either, or any proportion better befitting significantly increasing wait time.
All I understand is, that a process needs significant more cycle time now. I have no idea what was achieved before & after the change or how buggy both implementations are _and_ how that compares to what has to be achieved in order to provide an 'acceptable' gaming experience.
The answer to 8 minute turns is no. The answer to 30 second turns is no for most of the game.
I want to play the game, not wait on the AI. 150x30s turns is an hour and 15 minutes of doing nothing but waiting on the AI to move, should this last 150 turns.
Ok, interesting. You perceive the waiting time as "doing nothing", as a complete waste of time!
Of course I want to play the game too without pauses, but given a significant stronger playing AI, I probably could use the 'in between'-time being freed up for doing something else, especially if I could prolong the pause along my needs and return to the game whenever I want. (Probably thats a leftover from old PBEM days.)
Another aspect is the "even playing field". When playing I like the illusion, that the computer players are playing the same game. But I know, they simulate and simply try to entertain me.
So I have NO PROBLEM at all with "cheating" (extra resources, magic view etc.), alone the word is wrong, "they" just have other rules. One of them is that they have much lesser time.
I play slowly and need many minutes per turn (enough hectic on the job). If done right, I could do in the pauses "neutral" city-management ... Also could the animations of the first civ be shown while the moves of the second are calculated and so on.
I do not like waiting. I don't want to "defend" long waiting times (I'm in no way responsible or something).
And I know, that not all can happen as quickly as I wish.
