What made one work where the other failed? Does it just feel more natural for Link to be a wolf than Sonic, or is it because of Zelda's wolf gameplay being close enough to the original to feel familiar, yet new enough to be exciting? Alternatively, did you dislike both, thinking they were both gimmicky?
I think Wolf Link succeeded where The Werehog failed because, while both were somewhat gimmicky, Wolf Link managed to overcome the gimmick with Midna, a rising sense of majesty, and stellar gameplay. I mean, how awesome is playing Zelda as a wolf? Now think of playing Sonic The Hedgehog 2006 as a wolf...ugh.
EDIT- fixed a typo
