I like the academy the best (so far anyway, remind me sorta of the institute from fallout 4). Initiative are 2nd, but haven't played them so I could end up liking them more, apparently they are like the illumanity or something need to play them next. Or maybe they are more the corpo faction than illumaniti, not sure. Humanity first reminds me too much of the other "FIRST" that is going on today in the US. I'm pretty sure its meant to be too, its pretty on the nose. I know people are complaining of political stuff in the thread, but I'm mostly talking about in-game but there is in-game stuff related to real life stuff going on. Resistence is default faction I guess and reminds me of "humanity only, wont kill aliens except to defend humanity but ITS NO ILLEGAL ALIENS!" is what it seems like to me, literally, almost worse than humanity first and worse in some ways, at least humanity first is upfront about hating outsiders (except at least resistence likes other people, humanity first hates everyone probably each other too) lol.
Then got the servants, they are like humanity first but for the aliens, but seem fun to play for an easier game, they are pretty evil I guess if you want to protect earth. In my test game, they ended up getting everyone nuked lol. Which I shall add, nukes should be a lot hmm...harder to use. But guess thats balancing
The Protectorate...well...I don't really want to play them but I'd want them as an ally
Exodus is actually really cool, fight for position for 2nd for me, though wouldnt be #1. But I always thought a mass migration off a planet is pretty neat and different.
Maybe there is more to the factions than that. But in any case, I won't ever like humanity first. but maybe the others I'll find out more details overtime and like them more (or...dislike them more lol)
