People want to feel entitled so they can complain. If you really look at it, a Patreon subscription (or any other site, doesn't matter) is not an abiding contract. There's nothing teeling "if you give money to that person, they are forced my law to provide what you want". Yet, amusingly enough, a lot of people treat it that way... Funny, right ?
The reality of it is, Patreon and the likes are really more akin to donation. Actualyl scratch that, it's exactly what it is : donations based on a voluntary choice. But when people get pissed, they'll lash out at anything and anyone just to feel justified in their anger, and to not have to admit they are responsible for that gamble.
Sure, there might be a moral obligation (sort of) for the dev to deliver however they can, but nothing legaly binding.
And now, watch this post get drowned in facepalm reactions and people quote me to call me a Mulan brown-nozer.
Now that's interesting... Do you mean that you can tweek what "effects" from those "routes" of sorts are on, with that ? I don't remember encountering a dream sequence last time I played (it was a while back admitedly)...
