Nice suggestions guys, I've always wanted to play Katamari but I never got around to it. Banjo and Marble look interesting too.
Killer 7 is completely bonkers, I played it when it first came out and I can still remember it vividly because it's so odd. Iwazaru in particular is a very odd character. Killer is Dead also looks strange although I haven't played it yet. Suda has a unique style and all his games are unusual.
and when he crossed the bridge the phantoms came to meet him
