Radiant Dawn or Zack and Wiki?

[Hyperion]

I don't know if this deserves its own thread (most likely not XD), but I really need opinions.

 I finally have enough money to get another game after buying Galaxy, and I really, trully, do not know if I should pick Radiant Dawn or Zack and Wiki...So, I need opinions. Which game would give me the most value for my money? A very good, lengthy strategy game or an awesome new IP?

I have to say that I don't have any preference whatsoever right now. So don't even bother saying I should buy which ever game I think I would enjoy most (I want them both equally, but I can only get one). Because even though I loved Path of Radiance, and I wanted its sequel since forever, I also really want to try out Zack and Wiki to experience something new and refreshing. I want to buy Radiant Dawn because I know it will be another great game from Nintendo. I want to buy Zack and Wiki because I have been hyped for this game for months and I also want to support Capcom, not to mention the great reviews it's received.

So, for people who have played either game, or better yet, both--what do you think I should do?

P.S. Which ever game I ultimately buy, will be the only game I get for December. My next one will be Brawl most likely. If I get one, I would have to get the other after Brawl...and I really want to play both. Omg, I hate this!
