I got Zack and Wiki, but I honestly don't know why IGN tried to hype it to death. I find it's a fun little puzzle game that's meant for kids and no more.
However, I might be turned off by the whole animu shtick and the fact the whole anime club at SFU would try to be like Zack and "munch" on chocolate bars all the time and make similar noises.

Yeah, that might be it.
I'm willing to give it more time after Paper Mario I think.
