Knack outsold 3DW only in the UK for a few weeks which is equivalent of a 2k difference in the UK which within a few months Knack will be left behind as Mario keeps going like a marathon runner Knack won't hence why the are people trying to give some reason as to why people were harping on about UK sales back then.
Knack was helped by the fact that it was a launch title I'm willing to bet if it wasn't present at launch it may have sold less as just a title released later on.
