I wish that were true, but people pushed Zack & Wiki heavily and no one bought it (I have to admit I only bought it when it was $20, but I didn't have the cash at the time to pay full price).
IGN said on their Wii podcast they're several hours in and they're absolutely loving it. They actually said it's Game of the Year material and is the game to beat (I assume they mean specifically for Wii games, not overall GotY).
I'm also starting to get geared up for The Conduit. I'm just so happy to see so many good games come out on the Wii this year after three years of just being terrible. I actually see myself buying more Wii games this year than 360 at this point. In fact I'm probably going to sell my copy of The Force Unleashed (360) to finish paying for my preorders of MadWorld and The Conduit.
This Wii talk has me wanting to go crack open Tenchu or Deadly Creatures right now. Time to dust the system off.
Oh, did you ever play No More Heroes? By far one of my favorite Wii games and I'm looking forward to the sequel at the end of the year/beginning of next year.
