The risk of failure is used as a tension building device which can be mitigated somewhat by careful planning and good tactics. Sadly, there are times when lady luck turns her back on us, laying waste to even the best strategies. Good games mitigate this with the opportunity to make a dramatic comeback. However, I notice an alarming tendency for pessimism among certain segments of the video gaming populous. When they're having a good streak it's what's expected, but when fortune turns foul then RNG has screwed them again (rather than the inevitable results of probability).
My inclination is to dismiss such individuals as ill-tempered teenagers, but the reality is this sort of disdain for chance is extremely prevalent among board gaming communities. Statistics gathered from the database website board game geek strongly indicates that the community there dislikes games that utilize randomness in the mechanics. It's a sentiment I can't really relate to since, to me, nothing is more boring/frustrating than knowing what the outcome is yet being powerless to change it. If I were to play a competitive match of chess or "go" against a grand master, my defeat would be guaranteed. On the other hand, if the game has an element of chance then the possibility exists for a different outcome even in the face of a vastly more skilled opponent. That's perhaps overly optimistic way of looking at things, but lets face it; real life has a lot of RNG, and I don't want to hate life.
