People care because stories do universally well across reddit, and people who are starved for karma will inevitably abuse this trend to craft the perfect sob story; it will be well-received by enough of the subreddit's active voters that it will make the front page no problem. This means one less quality post about the game proper will be up there for people to see.

If you want to read it in the tea leaves, so to speak, take a look at the stories that all make it to the front page. Certain buzzwords are ubiquitous, many of them coined by the sub itself, and thus are more well received.

Is it any coincidence that as soon as someone strange coins a term for "Kinderguardians", that every good story for the next couple of weeks necessarily involves the term? Or when "become legend" takes off that little tales are popping up left and right about a new player who suddenly seized greatness making for a once-in-a-gaming-lifetime experience? How about "Squeakers"? Every story about an annoying player that hits the top has that player be emblematic of a grab-bag of stuff the sub hates: cursing stupidly, eating during the raid, interrupting everyone - and above all - not understanding the game. Then, OP, who has heretofore of course been silent and perfectly competent, strikes with the most perfectly timed and judiciously ironic comeuppance.

I list all these examples to show you the slippery slope we've already encountered: heightened reality or outright lies that play to the increasingly in-jokey and insular, impenetrable community. Every new term and shared experience does bring people closer together, but also adds to the karma-mine for anyone who is cynical or attention-seeking enough to exploit it. You have only so many spots on the front page, and users who have been posting things that aren't flashy, funny, or incredibly detailed, see that there's only a few ways to really make the front page. They might not have the skills to code a page to help you find dead ghosts, but they have the time to write a story.

Real-life stories are the ultimate version of these - the final connection making Destiny something that brings us all together. This can elicit the strongest emotional response -> the most attention -> the most upvotes -> gildings. Once a deceptive someone sees that these work, they're totally willing to spend time to make one catered just to the sub's tastes. This happens all over reddit, and people don't want to see it come to r/DestinyTheGame.

That's why.
