Last night and today I've been reflecting on the game's story via FF Wikia. I was unsure at first, mainly I was annoyed at Jecht being Sin. But I've looked past that and think the story is excellent and a very clever one at that.
Some slight similarities with The Matrix (although with a unique take) which is my favourite film. Aspects of atheism/scepticism VS religion and even racism is and was a very mature topic for a game, especially back then, to tackle, especially considering the number of kids that played it back in the day. If it had been more overt about it I imagine there would've been media controversy in the US about it.
The whole idea of the spiral recurs many times in the game; not just Sin's purpose, but Yuna and Tidus taking after their fathers, and Yuna and Lulu somewhat following in Chappu's footsteps. Plus Tidus' Zanarkand is in a spiral of reliving the same memories over and over.
The core concept of Tidus' Zanarkand being hinted at throughout the game was clever, but something you can only appreciate when looking back at the events of the game as a whole.
Seymour didn't turn out to be as good of a villain as he was in his first half, but they still contextualise his madness later on, though would've been nice if there was a bit more to his character development.
So yes, this game's story is a masterfully crafted one and I may collate my thoughts into a finer essay and post a thread about it. What shocks me is that this game gets stick from some fans, which I've noticed while listening to some retro RPG podcasts and watching some Youtube videos. I hope these complaints aren't due to the story, the linearity I can accept.
That's my core problem with the game. There was nothing stopping them from doing a World Map, but they chose not for design rather than technical reasons. The travels to each temple could've been left to the player's choice. Plus we don't see enough of the Ronso homeland or Bevelle or other places. Where are the town folk and what not! If this part of the game had been similar to FFVII I may have been tempted to rate it beyond that game.
Hell here's another idea they could've used in X influenced by VII: the opening Zanarkand portion should've been an hour or two longer, fleshed out Tidus' normal life a bit more, and trick players into thinking this was where the game would be based, like MGS2 as well. Seems to be have been a common theme back then haha.
The music is damn good. Listening back to earlier tracks is very nice, fills a hole that I've felt is missing now I've finished the story, that post-game depression haha. And though I didn't like blitzball mini-game, I'm glad the sport was in the game, just seems like a nice little side-story.
