niniendowarrior: Never played Killer 7. I'm pretty sure I would have just quit even if I guessed that one.
mrcrispy83: I haven't played it either, but got it from reading the hg101 article about the series.
Oh, it's brilliant. It took on rails shooters to a level you couldn't imagine they could go to. It was called out by a few known critics of gaming when it was released, but it's one of the most well-done on-rails shooters I've ever played, and it's got a really cool art style to boot.
The "smiling...whatevers" thing came from the fact that the enemies are called "Heaven's Smiles".
EDIT: Actually, in general Goichi Suda (aka Suda51) is a really good game designer. They just take the right mindset to really appreciate them, especially with how varied they are.
