I just picked up the Inuyasha Playstatin 1 game and am having fun with it.
The gameplay is pretty typical of your standard fighter game. Only three different atacks(with of course hi/low variants) plus a power move. It uses 2D animation not 3d. The one really cool thing is they really did a good job getting the drawings to be perfect and using the original japanese voices.
There is a simple story mode where you go around collecting shards by battling others.
Then there is a two person fight mode where you and a friend can pick any character - Inuyasha, Kagome, Sango, Shippo, Miroku, Naraku, Sesshoumaru, Kagura, or Koga and engage in battle.
Its a fun game for only $14
