Sounds like it's going to be optional, phew.

“We opted to just go pure RNG for the initial release in early access just to see what was going to happen,” he explains. “We see the people that have really bad luck, and they are really, really angry over it. So, we're going to help them. We're going to add modes to the game that are going to go with things like a loaded die, and that's going to be a bit more manageable. We'll still keep the option of having full RNG in there. We'll experiment with that throughout early access, and see what we should make the default option. That's one of the things that will be driven by the analytics.”
