Im sorry superslug but that doesnt really solve his dilemna...superslug said:Even if railing/work needs to be done elsewhere, I usually keep a fortified stack of workers beside/near core production cities, especially in 20k's. They typically get used for pollution cleanup, but every once in a while I need to dump one in due to one turn starvation.
The reason I mention this is because such a stack can get around your stated problem. At the end of a turn I sometimes irrigate a few target tiles, reducing the shield production and adding a turn to prebuild. I then remine those tiles the next turn.
I know what he means because I have been in this situation.
Hes talking about when you might or might not need to change a prebuild depending on what free techs you get on age change.
(Re read his example, youll understand).
Then your strategy does not work. and I would like to know if changing tiles if strictly penalizing yourself for something like that would be possible.
EDIT : I now read the rest of the thread, and totally understand your reasoning for still prohibiting this, but most of the ideas you mentionned are not pertinent to the specific case (luxury slider, workers etc...)
