While I personally would not place Katamari Damacy (2004) in an undisputed "best game ever" position, I certainly think you're valid for doing so. After all, it has a cool, unique concept that it executes pretty much perfectly.
Also it has a crab with a gun too, did you know that?
I really do want to finally play it now that it’s emulating really well. Even aside from playing at more than Drakengard 3 FPS I never had a PS3 to give it a go in the first place
