Not OP, but I think part of the reason Create is always so intimidating for me because it uses so many Minecraft mechanics in such crazy and unexpected ways that it feels like it must be absolutely janky as heck, like there's no way this can possibly work reliably. But if you can get over that and just trust the system, it really does work, and it's truly impressive. It's a crazy mod. It can be pretty tedious, depending how it's tuned (and I don't think it's tuned particularly comfortably out of the box, and most modpacks honestly don't do a great job tuning it either) but it's really, really slick and the more I use it the more I actually like it, it's sort of like playing a different game though, and I know some people don't like that aspect of it. It's not very Minecraft-y in some ways. But in some ways, it's much better.

From what I've found, I think the best way to really experience Create is to get into a modpack that really forces you to. Something like Create 2 Mekanism, or Create Above and Beyond.
