I guess I might as well actually make a case for my choice as well; Final Fantasy X remains the game with one of the most fun postgames for me and has kinda thrown a shadow over so many of the JRPGs I've played since, as it just keeps pushing the combat further and further, way beyond what you get in most games. For most games have basically an "Omega Ruins" kind of dungeon with an "Omega Weapon" kind of extra boss and that's about it. FF4, 5 and 6 Advance also more or less did that. While FFX lets you go so, so, so much further beyond. Best way I can describe it I think is, it doesn't leave you hungry for more at the end of it. So long as you enjoy its combat, FFX continues to provide. Monster capturing is actually fun somehow, in spite of being just grindwork it remains a good balance of not taking too long and waiting with good and interesting rewards in the form of extra boss battles, which are just fun to go through, while consistently having you get and feel more and more powerful.

It has its share of valleys ofc which are pretty notorious, but they're basically just the celestial weapons' sigils which for some reason take more or less low effort minigames are require you to achieve absolute mastery of them. I maintain that the minigames themselves aren't actually bad, if they'd just been a slight diversion they'd have prolly generally been remembered fondly. But the sigils throw all that out and require way too much from the player. It's like if they'd locked Zidane's final weapon behind getting 1000 jumps on the rope, you just don't do that. But, overall, I don't care that much. It got to me the first time, but I've played this game so many times by now, and fitting to the poll question, replaying again and again has only made it better, not worse.

For the most part, FFX's postgame left me wishing more games did more like it. FFV's combat for instance is so cool, but you reach the point of being utterly unstoppable way earlier, and I just ended up being hungry for more with the battles - even against endgame foes - feeling more like a formality and chore than even the capturing part of FFX ever did.

As for the art direction, well, it's not why I voted it, but FFX is doubtlessly the most beautiful looking game in the series for me. I love the aesthetic, the designs, the animations. It's certainly a frontrunner in that category for me.
