Thats a whole 'nother chapter. Sids Sushi is the One, put it in your holy city (you hopefully got a priest to build the shrine for whatever religion most of the AI are) along with Wall Street since you have such high costs using these corporations. Try to obtain as many coastal cities as possible and the resources of course. One tile islands are very nice. Executives cost 200 hammers at marathon, and I have tried just purchasing them for 500ish gold a pop. You can turn off research at medicine if you have Physics already and the great scientist. Pop off a golden age here if you can to go into the -25% corporate cost civic; maybe you can take environmentalism work later after most everything is bought. National Park you can probably put in your highest food city along with Globe so you dont have to raise the lux slider to compensate for a single city's high growth rate. Another thing is to obtain Mausolleum of Mausolos as early as possible. Its worth 2 golden ages at least. I would hate to build it, rather take it, but perhaps it is indeed worth building. I havent had it in time in either of the two games so far. GP Needs Rundown Scientist-academy Priest- shrine for uber religious city (worth +70 gold when put in last go around) Scientist- education Merchant- Sushi (free at Econ) Scientist- Golden age (free at Sci Method) Artist- Golden age (free at Music) Spy- Golden Age (free at Communism) +3 more of various types for your 4th golden age Total of 96 turns in golden age (about 20% of the game). Things for further study: Research post medicine/refrigeration- go on to Future Tech if score is still increasing? What is the value of future tech? Christo Redentor- worth it or no? No more need for golden ages to civic change and allows for easier environmentalism.
