But what if someone that's done the overwhelming majority of things in this game decides to come in and tell you, from personal experience, that your argument holds absolutely no water? That everything you're telling people to go do, even if they don't enjoy it, also takes no more than a handful of (repetitive) hours each to complete? Then what?
Hurp-a-durp let's go collect all the Triple Triad cards, youse gais! Oh it's been maybe 35 hours dedicated to this expansive, 220-card system that's been built upon for three years and we're already finished? Welp!
And most of that involves repeatedly grinding instances to get random drops, not even playing the Triple Triad card game itself. Which is even easier than when I did it because they've removed the timers from NPCs, removed the Random ruleset, and they tell you in-game whether you've beaten the NPCs and if you're missing cards from them still without having to rely on a third-party website.
Example 2: The sightseeing log doesn't take "days" to complete, it takes maybe two hours of in-game effort. As with the "fishing endgame," most of your damn time is spent not actually doing the thing you're trying to do while looking at a third-party website every couple hours to see if the thing you want is even available or not. HW and SB sightseeing logs, the pair from the Kugane jumping puzzle aside, largely don't even have time or weather conditions and you can merrily fly around and pick them all up in like 30 minutes. Mostly even without a cheat sheet because they've got giant floating balls drawing your attention to them from half a mile away.
All of which ignores that this isn't even the subject of this thread, which is decidedly in the realm of breaking the status quo and not doubling down by adding in more of what we've already got for the nth time.
