Game developers sometimes make the “randomness” favor the player, because of how we perceive randomness and chance.
For example in Sid Meier’s Memoir, this is mentioned.
Quoting from a review of said book:
> People hate randomness: To placate people's busted sense of randomness and overdeveloped sense of fairness, Civ Revolutions had to implement some interesting decisions: any 3:1 battle in favor of human became a guaranteed win. Too many randomly bad outcomes in a row were mitigated.

Some threads on randomness and perceived fairness in video games can be found here on HN too, for example https://news.ycombinator.com/item?id=19399044
The original link being discussed in that thread is 404 now, but archived copies of the original link exist such as for example https://archive.is/8eVqt
Dispatch too. If your odds are above a certain threshold, the mission is a gimme.
I think XCOM does this as well.
Games like Battle for Wesnoth which have it implemented right, you’ll look at a 90-10 scenario with 2 attacks and end up with the 1% scenario. Enough to make a man rage. I have degrees in Mathematics, I am aware of statistics, and all that. And yet when I played that game I would still have an instant “wait what, that’s super unlikely” before I had to mentally control for the fact that so many battles happen in a single map.
Was good because it identified a personal mental flaw.
