Can I just drop an army on one of their planets and wipe them all out before even establishing communications with them?

Yes, so called "first contact wars" are in; but once you invade the first planet then you effectively make contact and so you couldnt annex an entire empire by simply not trying to contact them. Of course invading a world during first contact has implications long term on how much that species will like you. Hint not a lot!!

Yes, in one of the dev. diaries they explained about "The first contact war" you simply need to change your politics in The first contact reaction from neutral to aggressive and start attacking their fleets and planets.
This doesn't seems the most friendly way, but Blorg may allow that.

Like in most of our games, occupying a planet with your armies does not mean it immediately becomes yours, of course; you need to demand it in the peace talks. There is a notable exception to this rule though; so called “first contact wars”. Before you have established communications with another civilization, it is possible to simply attack them and even take one of their planets (but once you take a planet, communications are immediately established.) Of course, such early hostility will never be forgotten, and will sour your relations for the rest of the game…


Indeed it was the Dev Diary on War and peace, (https://forum.paradoxplaza.com/forum/index.php?threads/stellaris-dev-diary-20-war-peace.907257/) just went and dragged out the quote from the end of it that tells us this.

i know, it called Crusader kings 2: bullsh*t sunset invasion

I still don't get why people get angry about Sunset Invasion. It's a nice, discrete DLC that doesn't have any features you "need" for other parts of the game. If you don't want it, don't buy it, or turn it off if you got it in a package or just want to play without it.

More historically, you might consider the Mongol expansion a first contact war. Colonisation of Australia and the Americas, too.

It will be viable in the start of the game, mid game have chances that you will just make yourself an enemy for the entire game who will enter all the alliances which were built against you, late game this tactic is only against 1 planet fellows
Tactically it is most likely a poor choice, but gosh darn, it's really cool too.

I don't hate it, its is fun and cool, but its f*cking annoying when you are playing somebody who near the atlantic ocean, when i managed to build a holy irish empire, these bastards came and took all of my Spain and half of the france and only after that i beated them and they changed their religion.

Every time I play as Alfred the Great I have completely mopped the floor with the Aztecs. It probably helped that I had Iberia, France, and all the British Isles.

well, they weren't actually mine, i just made them fall apart(spain get all the land and some of france) and wanted to kill them, i forgot about aztecs and they took the advantage.
And i got into war with scandinavia for noorway and forgot about these little americans.
and i noticed only when they got france and spain xD

lol i said and at least 6 times

A better question is - can I just ignore diplomacy and wage war left and right? Without selecting my war goals and whatnot? It made sense to be limited to warring a bit in the historical titles since you could not really exterminate a whole race and public opinion sort of mattered, but in space why whould I be concerning myself what a xeno things before I purge their foul existences?

technically can't, but if you want and will try you will be forced to deal with big alliances that can be unite forever
