The-Site-Which-Shall-Not-Be-Linked has given us an entire shared language for recognizing and discussing age-old story elements that we've experienced for our entire lives yet never explicitly discussed. No matter what one thinks of the items on any individual page, that alone is invaluable. Plus, it's the single-greatest cross-linking piece of time genocide I've ever come across on the Internet, which is worth something in and of itself.
More on-topic, while all of the entries as-presented may not be suitable for a wiki article, I feel like the majority of them cross over from individual pet peeves to negative elements that hinder just about any campaign they're used in. I mean, I don't know a single player who likes a challenging 20-minute-long mission with a very real chance of death in the 19th minute, or having to sit through five minutes of dialogue every time they restart a difficult mission, or a twenty-wave enemy wing, or anything along those lines. These complaints are bigger than individual players.
