Quite good game with HORRIBLE dubbing.
Gameplay - there should be better story put in game. I don't get it: there were so many episodes of anime, a lot chapters of manga and what we receive? - easy game, leading us from fight to fight. Of course it's fighting game, but I'm quite disappointed. Now it's time to get to fighting system - it's not that complicated (comparing to Tekken or SC), just for casual player like me, who likes DoA games. Players aren't limited to go forward-backward and strafe - you can go in every direction. There are few combos (mainly concentrated on TAG actions - as is whole game), reward system for action's style and of course special attack, placed on O (e.g. Hiraikotsu). As for the characters - you'll find almost every main character from the TV series (even Shippo-chan or Naraku). Ok, it's time to move to the next part...
Graphics - first I'd like to say it isn't as good as Tekken's 5, but very good. Well, these two games are totally different, because I: FC is based on RenderWare engine and uses cell-shading technology, which suits anime roots of the game. Also characters' animation is very fluent.
Sound - bah, the worst part of the game (and reason of such low score). Maybe it's subjective, but I hate English dubbing in anime-related stuff. When I heard Inuyasha's "Shikon Jewel" - I thought: "is it really Inuyasha or **** from GTA: SA?". Bandai should leave option to choose from Eng/*** sound; English in this game is really disgusting. Besides every sample sounds like it's 22kHz, not normal 44.1kHz.
Ok, time to summarize all this. If you're normal player looking for fun, you will be quite disappointed - game is above average and straight-going.
BUT - if you're Inuyasha fan (such as me) it'll be more than worth buying, especially if you have someone that shares your passion for the series.
It is really fun to play in Black Pearl level as Inuyasha vs Sesshoumaru and using Kaze no Kizu or Bakkuryucha (Backlash Wave). Game has my recommendation.
That is all!
