The biggest problem I have with threads of this nature is that they tend to follow a pattern.
1. Poster #1 asks, "where are the video game / anime examples?"
2. Poster #2 supplies points A, B, C, and D.
3. Poster #1, or more likely Poster #3, then proceeds to dissect each individual point, saying that A can be found in this genre also, B in a different genre, C can be found in previous editions of the game, and D can be found in many other RPGs of earlier days. Then they conclude that Poster #1's point isn't valid.
4. Poster #2 gets frustrated, because he feels like he wasn't being listened to at all.
It's like person #1 saying, "prove that Mr. Jones is a computer technician."
Person #2 says, "Mr. Jones works for DataCorp, his job title is 'I.T. Staff,' and he spends all day fixing PCs."
Person #1 says, "Well, Mrs. Smith works for DataCorp, too, but she's not in I.T. Furthermore, IT Staff is a broad job title, and covers not just computer technicians, but Network Administrators, some coders, and even the head of the department who hasn't touched a screwdriver in years. And lastly, I just spent all day last week rebuilding my tower to get it up to snuff to play my newest computer game, but I'm not a computer technician. Therefore, your facts don't really seem to hold water."
Person #2 says, "ARRRGH!" because he feels like person #1 is being deliberately obtuse (which in my little fictional example person 1 would be.)
So a lot of times, the examples that are given need to be also evaluated in their context, rather than dissected. If someone gives lots of examples that all apply to one thing, but could also apply to a bunch of different things too, it doesn't mean they're valueless. They might be circumstantial, but a large amount of circumstantial examples about the same thing should be reason for at least pause and consideration before dismissal.
