Those are general hours when giving a comment about a game. So basically people give a comment about their experience, about approximately the amount of hours which is been shown as "general". That doesn't mean the people who gave their comments actually finished the game. I've also given comments about SSBB and Endless Ocean for instance while I haven't finished those games, but am still playing them.
