(Why would go through the trouble of doing this? I transferred my HQ to a city that gave all units 3 plus unit tier bonus armor and +1 shields. I've been friends/integrations with 4 NPC's on a large map using the celestian secret tech. Vanguard get another doctrine that boost influence rewards. If you're celestian you also get a doctrine that decreases the wait time for new quests. The negotiator doctrine give you a influence discount when you buy stuff from them. The emissary doctrine with give you more influence from completing quests. Getting 3 or more NPC factions to like you is doable but it takes a dedicated effort. However, if you take the "do quest instead" option when their demands show up, completing that quest will give you a slight relations penalty with the other factions just like doing other quests.


I forewent the DLC at first to get a feel for the game and there was more than I could handle already, especially since they were updating all the time. For now, Vanilla has SO MUCH you will not need any DLC. Accepting their demands also gives a +5 relations bonus. If you can, wait for a sale and get the season pass. Buying stuff with influence from them increases your relations without upsetting the other factions. Getting two NPC factions to like you isnt that hard.
