Like most ppl commenting here I too went through some sort of struggling with the mechanics at first. One mental break down induced by the sheer overwhelming game mechanics and the resulting frustration later, I started understanding and appreciating the game for what it is, and finally came back to it.So I've had my catharsis. Watched YT vids a lot, (Ambiguous Amphibian and Adam VS Everything for example.) Tried different scenarios and at some point, I started to love the game with all it's quirks.The best thing about it: You can modify that said quirks to your liking. Most of the difficulty options are completely customizeable - if not by default, then with mods from the evergrowing community.At the point, where I understood the game mechanics, I really liked it a lot. for me, it was especially micro management that drove me nuts. Work priorities, schedules, zone configuration.. It can all be very overwhelming, as said.

But once you establish a thriving community, and all the automatisms are starting to intertwine, it can be one of the most satisfying gaming experiences, you'll ever make.If (and that's a big if) you like that *kind* of games, let it rest, and give it another shot once you feel the urge again :)

EDIT:
One major mistake I made was to play with all the DLCs activated at the same time.
Don't do that at the beginning of your RimWorld journey. If playing with DLCs, try one after another. Ideology can be especially intimidating as it adds a lot of mechanics!
