(not sure if this counts as it is Clover Developed....)
For me personally, Okami is my favourite Capcom game. I am a huge Zelda fan, and this is definitely up there with the best Zelda titles for me.
The artwork, artstyle, soundtrack and game world drew me in to a fantastical representation of Japan. Combat is fast and enjoyable with a wide array of enemies, and the art brush is an excellent and unique addition. A great combination of overworld exploration, "dungeons" that are actually proper parts of a lived in world, good puzzles and a game story so big that many joke it is a trilogy of games in one!
It also helps that Amaterasu is a well represented character, and a great likeness to a real dog imo, and though silent, can be extremely funny at times when acting like a typical dog.
I love this game, the HD version is amazing, and the Okami complete works is a prize treasure in my collection!
