^I had the same thought watching the battle video.
Animation man, animation.
Yes Xillia will look sharper and have much filled out environments. But you said the animation was a step up, which is craaaaaaazy land talk since Team Symphonia animation has not advanced at all in 8 years.
wait, do you mean the cutscenes? because who cares about the cutscenes? the Graces one has that really awkward stage play look to it while Xillia is stiffer and more appropriate for the anime look, but both will be stupid and dumb regardless.
The combat and everything looks way nicer in Xillia and that's what actually matters. Stories in Tales games are C-tier anime at best. The cast can be entertaining, but that's usually from supplementary dialog and not the lame pantomiming cutscene shit. Like, Rita's strap-on moment from Vesperia was all text.
though, to contradict myself, I watched the Xillia video right before making this post and the battle cutscene at the end looked nice. Doesn't seem like they need the anime ones anymore because the game looks nice enough on its own.
