Hmm.... just thought of an idea which may exploit this further even during normal period (I hope I don't get condemn for always coming up with ideas of exploiting the loopholes
). I will not actual use it for any competitive game though. Maybe just only once during SG just for the hack of it.
(1) Use a fully corrupted city with extreme overlapping - perhaps ICS in outlaying places.
(2) Do a few rounds of whipping/drafting on this city so that the first citizen is unhappy without entertainers.
(3) Prepare some workers to add to this city.
(4) Unwork all city tiles from the other cities and give it to this city.
(5) Add as many worker as the city can support.
(6) Unwork all the tiles and give it back to the other cities.
(7) Make all the citizens scientist except for one who will be unhappy to ensure the city goes to riot.
(8) There. You got your research powerhouse on the once fully corrupted overlaying city without using much tiles.
(9) Repeat for as many city as you want.
Again, please do not condemn me. The idea just pop into my head as I read this again and it sounds cool enough that I like to publish it.
