How many copies does a game have to be sold for it to considered successful?

good is 500k

succesful or ecellent is 500k

 arbitrary numbers make no sense, every game from every publisher will have different expectations for success, I really doubt

I really doubt, say Atlus, to expet any of the games they publish to sell half of a million copies
