How does culture work?
I played yesterday for Advent Loyalists again and this time tried to go heavy with their cultural upgrades, which probably for the first time gave me more of understanding, what is so special and unique about the whole faction. Was totally unaware of things, which give you the map of cultural "strength" across the system, or the fact, i can see enemy grav-well under influence of my own culture for example.
Anyway i found out, i actually know pretty little about the nuances, how the culture works in detail... i mean, i know, you need to build those broadcast centers ( temples of communion), and it starts spreading from them, or that it targets planets allegiance, or that it affects various things like income rates or weapons damage... but as i used to play almost exclusively as Vasari, i built them only if i had to as a reaction to what enemy does, i mean i was rather reactive than proactive with culture....
so i have 2 questions...
1. Advent are supposed to be the main "culture" faction, what does that exactly mean? Is their culture actually stronger, always pushing the TEC/Vasari one, or its more about having the cultural upgrades/buildings sooner and cheaper? If i play for Vasari, max my culture research and build same number of those media hubs as the Advent Player (with maxed culture himself) on the adjacent planet, will it be a cultural "tie" or will his culture steamroll mine anyway, as its stronger by definition?
2. Should i build the communion temples at my border worlds primarily? I mean, because the culture rates get weaker with the number of jumps, its best to build them closest to the enemy, right?
