Overall, is the game in a state where people enjoy the experience? Are there any major game-breaking bugs or quirks? V2 is my favourite game of all time, I've been waiting for V3 since forever and I really don't want to be dissapointed when I load up.
For my two cents, if the release version of the game wasn't doing it for you, then this is still not worth it. 1.2 is ultimately just a somewhat cleaned up 1.0. It doesn't
feel different in any big way. So I'm inclined to say no, because you didn't get it on 1.0. 1.2 isn't a patch that's going to change anyone's mind, if it was already made up.
As to whether or not that feeling is something you want...that's obviously harder for someone else to answer and I'd really recommend watching a stream to get a better sense of the game than asking for a text post. If you really pressed me for an answer, I would say
no. There are definitely fun elements of the game, don't let anyone tell you otherwise, but even by Paradox release standards V3 is really kludgey and awkward (Stellaris release day player here, so...). I quit every game by about 50-60 years in because the game literally just gets too frustrating to engage with.
But y'know I've also still done 250 hours of play. So when I say that there are definitely fun elements of the game,
those elements are genuinely fun. I don't want to downplay the successes of the game where it works, it's just that by far the foremost emotion I associate with my playtime is
frustration.
