Of course! I'm only getting the Wii U just for the games. I played a demo of Hyrule Warriors at Game Stop, so I really want that.
If you played it and enjoyed it, and you don't feel you'll get bored of it's playstyle go for that first. That game has countless hours of content if you start playing the adventure mode along the story mode. I mean it's just the adventure mode that has a lot of content but it'd probably get less boring if you play both at the same time.
