Yeah, I've found it doesn't feel like a Super welcoming community. The documentation is well-written for the most part (for Sugarcube, anyway) but assumes a certain baseline familiarity that, not everyone is going to have. And if I were good enough at programming to just know how all of this works, I'd just be programming the game from scratch -- making an engine like twine is going to attract an audience that doesn't know what the fuck they're doing with computer, and it's bizarre and unkind to judge those people for not knowing the difference between 'div' and 'span' (I still don't! I won't even if you explain it to me, so don't try.)
This is what made StoryNexus so appealing, and why it's so frustrating for people to say to just use twine (or &c) when we complain about StoryNexus being taken away from us. StoryNexus required almost zero understanding of programming to use, and made it trivial to make game events. Sure, we got that in exchange for being much more limited in what we were able to do, but it struck that balance extremely well. Being told to just use twine is like being sad you don't have any linkin' logs and being handed a block of wood and a knife. Like yes, I can get there, but you have increased the difficulty and the time commitment here by a lot, even if it's now still technically easier than just pointing me at a forest and telling me to go cut down a tree. And yes, I can make a little statue of a dog instead, if I want, and I couldn't do that with linkin' logs, but I didn't want to make a little statue of a dog. I wanted to make a log cabin.
