Sales have generally been trending down substantially since FF7. [1] X and X-2 only sold better by merit of both being two games counted as one, and by being released and released on a zillion platforms.
I think in general though there's this weird paradox in games that things we think we enjoy can make games worse, yet it feels bad to try to 'fix' now. I think the best example would be quest waypoints in various open world games. It's absolutely painful to play without them now, but on the other hand when one actually had to pay attention to your quests and goals, it resulted in vastly more satisfying gameplay compared to what's gradually turned into some weird ritual across a million games of fast-travel to nearest location, bee-line to colored dot, skim text, repeat.
No idea who first said the quote (that's been attributed to Gabe Newell) but it's just so true: give players the opportunity to, and they'll optimize the fun out of your game.
