The issue the game has are simpler than that, which, again, I say as someone who actively wrote some of it: you don't have the liberty you think you do.
There's just a LOT to keep in mind when you write for DOL.
It has to fit the overall narrative (as people have mentioned, this includes that consensual sex is a pretty tough, and dominant sex is basically a no); it has to fit in the world technically (which is something Vrel usually does himself, and is a shitload of work); you have to make sure every possibility is covered (male/female Robin, just to name something, but also m/m mc/robin, m/f, f/f/, f/m, etc.), not to mention herm; you have to make sure you don't write anything that hints at kids (which, to be fair, I' was a huge proponent of, because it's how DOL stays just ambiguous enough); you have to make sure the entire thing doesn't sound disjoint from the other entries of the game; ...
TL;DR most people don't manage more than a few simple scenes. For good reasons. I helped with one of the least visited parts of the game, I'm sure, and whenever I revisit the game I realize just how much effort went to waste there. Talking literal months of effort, for barely any result (which I'm to blame for, I wrote it).
I love Vrel for the effort they've done on DOL but it just feels really stagnate right now. And I truly hope people keep experiencing this game for the first time(s) and loving it, I guess it's just not for me anymore.
