for science in general without taking civ into consideration: Holy Sites: 0, I really hate religious play despite the benefits. Thrilled to capture them in warring games though to pump monumentality Entertainment: 1 for coliseum IZ: 1-3, will skip if I've got bad adjacency/city overlap Encampments: 2, one in each spaceport city, more if I've got a frisky neighbor/good choke points Aero: Probably one in the latter spaceport city, preferably two more elsewhere for eurekas. Theater: this one's the hardest for me. If I'm playing on deity I might prioritize 3-5 of these before anything else other than maybe an early campus in cap to grab great writers and get culture online asap, then I might not build another one depending on city states/how many writers I can snag. If I end up losing a bunch of them to kongo/russia etc i'll build TD in just about every city after the campus and comm/harbor are down, with arch in the higher prod cities and art museums in the lower ones. City states are prob what warp this the most though. Campus: Every city. Comm or harbor: Every city, with a preference towards harbors. Happy with comm hubs too though if it means I can snag some merchants for more routes. Sometimes I'll even slam these before the campus. Spaceport: 2 just about every time, hard build one in a high prod city for the latter projects and purchase a second in a chop city. all that said, i'm still pretty terrible when it comes to getting the latter eurekas/inspirations, esp in the civics tree. i should really change things up to hit them more consistently but I usually start getting bored around t120 and just can't be bothered with them.
