Sega fans used to eat this game up and claim it to be the ultimate adventure.  It sure is adventurous!  It didn't become the all-time classic that gaming magazines thought it would, but Nights has some really spectacular graphics and leaves you with a pleasant taste in your mouth.  It's unlike any other game I've ever played and when you're done playing it, you think about it.  You think about how there's really nothing else like Nights out there.  That alone should be enough for you to look into the game.
