What is necessary to be a good PR in the first place?
Patience & Tolerance are the key factors. I mean, to be blunt, you're dealing with naive, bumbling, impatient, whiny idiots, and I'm not just talking about gamers here. People want things their own way, and a lot of times they will [sonic slicer] their way into getting it. It's like dealing with a child, except these children have you by the money balls a lot of times. As a PR person, your job is to not only try to make everyone happy while doing it in a respectful manner, but resist the unbelievable urge to tell them to [tornado fang] off.
And that's just doing it in person. Imagine trying to deal with gamers on a FORUM. They are faceless & they are fearless. They don't have to worry about looking like an ass to anyone they really care about or know, and boy do they look like asses. Look at what the Capcom-Unity USA forum had to deal with, and STILL has to deal with after the Legends 3 debacle, when they had NOTHING to do with it. Nothing.
This is why, while it is very awesome to give people input into the creative process like this, a lot of times it's a baaaaad idea. Especially over the internet. You have too many conflicting opinions and too many crazy people with their heads so far up their ass that it creates an ass-head loop paradox. Like I said, they are faceless, and they are fearless. And they are, for the most part, unsatisfiable.
