It was a love/hate relationship at first.
Bought it day 1 at Circuit City.
Hated it at first - however as I played it more and years later played it again - became one of my most favorite platformer games ;o.
Ironically the same thing happened to Banjo-Kazooie which is one of my top 5 favorite platformers of all time.
I plan to play it again for the 4th time soon.
