I hope they put the International content (Penance) into it - having originally played the PAL version, I find my desire for a replay somewhat culled, due to the lack of a challenging post-game battle. --- Check out my Quickening Guide for FFXII
They need to redo the character animation in the cut scenes
FFX had three or four (I forget) character models:
Battle model Field model low grade cinematic model high grade cinematic model
and then the prerendered CGI FMV's
All the models looked quite different from one another.
High grade cinematic model Tidus and Yuna looked Caucasian. However, FMV Tidus and Yuna looked Okinawan
And then in many of the cutscenes, because of the limits of the PS2, the animation looked awkward and jumpy, sometimes looking like it was on fast forward. I noticed FF XIII-2 suffered from some of this because instead of XIII how it only used the high grade character models for cinematic scenes, XIII-2 also had lesser scenes using the lower grade models (when talking to NPC's or sometimes each other and stuff)
That's why I'd of rather they remake the game so everything looks more consistent
But now that KH 1.5 HD looks to have redone character models, I guess there's hope but still who knows cause that may just be because of a different team working on it and their own choices...
