FFX low tier? Lol ok.
It is.
It is the worst of the 3d FF's aside from FF13.
Rock paper scissors battles that you use from hour 2 all the way down to the final hour, a linear character progression system which doesn't allow you to customize character trajectory until well into the late hours of the game, the same fucking monsters over and over (tidus -> dog, auron -> shell thing, lulu -> flan, yuna -> giant monster, rikku -> treasure chest, wakka -> cyclops). Not to mention the WORST side quests in the series.
The biggest compliment I can give X is its story, world, and characters. Brimming with personality and passion.
X-2 makes X its bitch. X is definitely near the bottom, the only ones I think are worse are II,
maybe III (though III nes gives it a run for its money), and XIII.
