Helpful hint: unless absolutely desperate with no land to spare, don’t upgrade buildingsI bought one and upgraded it a few times. I really wish I didn't waste the greenies on it.
Once you get neighbours with training centres and planetarium then you'll get plenty from launch boxes.
Yes, what are the BIG 3 that you can build up to 6 of each?Helpful hint: unless absolutely desperate with no land to spare, don’t upgrade buildings (the big 3 not withstanding) until you have 6 already built. Save the greenies for land.
I do agree that Town Hall is not something you need to upgrade asap. Delay it until there is nothing else to build.My apologies, I was a bit vague. Yes, I was referring to Town Hall, Terminal and Tower. By all means, upgrade at will. I was trying to suggest that building multiple item producing buildings (eg factories) was far more beneficial than upgrading a single building with greens. I suppose it depends on what the value of land is at decision time.
