I'm not a big FFX fan, but I'll give it credit for a couple of things.
First, the visuals. It may be a cliche, but they really are amazing. Both the FMV's and in game graphics are top quality.
The ability system is also pretty good. It allows for a decent amount of customization, while still giving each chracter a well defined path of development.
Although the music is nowhere near up to the standard of FFIX, it's still OK. A lot of pieces were forgettable, but one or two stand out, 'Servants of the Mountain' in particular.
There may be a lot of FFX bashers around, but the game's hardly short of support, is it? Just one look at an FFX review site will tell you that. It's one of the best-loved games in the series, and a fine game in it's own right. It's just not my idea of a Final Fantasy, that's all.
